Asparagus fern (also called emerald feather, emerald fern, sprengeri fern, plumosa fern, and lace fern) is toxic to dogs and cats. The toxic agent in this plant is sapogenin—a steroid found in a variety of plants. If a dog or cat ingests the berries of this plant, vomiting, diarrhea, and/or abdominal pain can occur. Allergic dermatitis (skin inflammation) can occur if an animal is repeatedly exposed to this plant.

Here are tips to manage this condition and minimize your dog’s discomfort.

Fleas are blood-feeding parasites that can infest many species of birds and mammals. Although fleas on dogs and cats don’t infest people, fleas may bite people if an area is heavily infested. Flea infestation is one of the most common medical problems veterinarians see, and pets suffer greatly from this condition. Flea bites can trigger severe allergic reactions in some pets. The intense itching caused by flea infestation causes pets to scratch and bite themselves. This can lead to skin wounds, skin infections, and general misery for your pet. Even if your pet is not allergic to flea bites, fleas can transmit serious diseases, such as bartonellosis (the bacteria that causes “cat scratch disease” in people), and other parasites, like tapeworms.

With many dogs living well into their teens, many owners wonder: When is a dog truly senior? The answer is that there is no specific age at which a dog becomes senior. Individual pets age at different rates. However, most dogs become senior at 7 to 10 years of age, and most large- and giant-breed dogs become seniors earlier than small-breed dogs.

Companion animals today have the opportunity to live longer, healthier lives than ever before. One of the main reasons for this is the availability of vaccines that can protect pets from deadly viral and bacterial diseases. Over the past several decades, the widespread use of vaccines against canine distemper, parvovirus infection, rabies, and other diseases have saved the lives of millions of dogs and driven some of these diseases into relative obscurity. Unfortunately, these diseases still pose a significant threat to dogs that are unvaccinated; so, although vaccine programs have been highly successful, pet owners and veterinarians cannot afford to become complacent about the importance of keeping pets up-to-date on their vaccinations.

Bad breath in pets may be a sign of periodontal disease that could lead to other health problems. Periodontal disease starts when plaque (a bacterial film) coats the tooth. Plaque hardens (calcifies) into tartar, a thick yellow or brown layer on the teeth. Tartar can irritate the gums, creating an environment where bacteria thrive. As the disease progresses, the gums become tender, red, and swollen and the bacteria continue to multiply. Eventually, the inflamed gums pull away from the teeth, creating pockets that trap more bacteria and food particles. The gums bleed, the roots of the teeth may become exposed, teeth may become loose, and your pet may feel pain when eating. If the bacteria enter the bloodstream, they can create problems for organs such as the heart, lungs, liver, and kidneys.

Gastrointestinal (GI) parasites include any parasites that live in the stomach or intestines of a host. A variety of GI parasites affect dogs and cats. They range from roundworms and tapeworms, which are visible with the naked eye, to microscopic organisms like coccidia and Giardia. Regardless of their size, GI parasites can cause serious illness and sometimes even death in pets. Some parasites are  zoonotic, which means humans can become infected.

Dealing with an injured pet can be scary and frustrating. In many cases, you don’t know how bad the injury is, and your pet may not be acting normally. If your pet is injured, the first thing you need to do is try to remain calm. If possible, try to determine how severe the injury is, but remember that caution is extremely important when approaching an injured animal. Any pet, no matter how calm or friendly he or she may usually be, can bite or scratch when in pain.

Gastric dilation–volvulus (GDV), or “bloat,” is a life-threatening condition in which a dog’s stomach fills with air and becomes twisted. Gas builds up in the twisted stomach and stretches it. This stretching, also called distention, is extremely painful and limits the amount of blood that can reach other parts of the body. When blood can’t reach body tissues to supply oxygen, those tissues can die. GDV is an emergency situation, and if not treated immediately, it can be fatal. While any size or breed of dog can develop this condition, it is more common in larger-breed dogs with deep chests, like German shepherds, golden retrievers, and Great Danes.

Hookworms are internal parasites that generally live in the small intestines of puppies, kittens, dogs, and cats. These worms attach to the intestinal tissue and suck blood and other nutrients from their hosts.

Many eye conditions in dogs require medicine to be put directly into the eye. This procedure can be relatively easy, as long as you follow a few simple guidelines. The most important guideline is to always put health and safety first. If, for any reason, your dog becomes so agitated that you feel you are at risk of being bitten, stop. If the procedure seems excessively painful for your dog, stop and get your veterinarian’s advice.

The most important guideline is to always put health and safety first. If, for any reason, your pet becomes so agitated that you feel you are at risk of being bitten, stop. If the procedure seems excessively painful for your pet, stop and get your veterinarian’s advice.

Liquid medications are prescribed to treat a variety of conditions. Some medicines that are usually prescribed as pills or capsules can be changed (compounded) to a liquid for easier administration. If you have trouble giving your cat pills, ask your veterinarian if compounding is possible for specific medicines.

Medicines in pill or capsule form are prescribed to treat a variety of conditions, but many dogs dislike taking pills. Some medicines that are usually prescribed as pills or capsules can be changed (compounded) to a liquid or a powder for easier administration. Some medicines for dogs come in a chewable “treat” form. If you have trouble giving your dog pills, ask your veterinarian if compounding is possible or a treat form is available for specific medicines.

Despite the adage about a dog’s nose being warm, cold, wet, or dry, any of those signs may, in fact, be normal. Many other signs can give you a better indication of illness in a dog. For example, any changes such as decreases in energy level (e.g., sleeping more), decreased appetite, or weight gain/loss may signal that your dog is not feeling well.

A number of human foods are dangerous to pets. Many of these foods may seem tasty to our pets but can prove deadly if eaten. It can be very tempting to offer pets food from the table, but pets should not be given human food unless recommended by your veterinarian.

Ibuprofen is the active ingredient in medications like Advil and Nuprin. Naproxen is similar to ibuprofen but is longer-acting; it is the active ingredient in medications like Aleve and Naprosyn. Ibuprofen and naproxen are widely used to treat pain, fever, and inflammation in people. Unfortunately, these drugs can be extremely toxic (poisonous) to cats and dogs. Toxicosis occurs when a cat or dog eats enough of one of these drugs to cause damaging effects in the body.

Pet obesity has become a very common problem. Studies indicate that nearly 50% of adult dogs and cats in the United States are overweight or obese, and that percentage increases among older pets. Obesity increases the risk for other serious health problems, including osteoarthritis, diabetes (in cats), heart and respiratory diseases, and many types of cancers. Overweight pets are also at increased risk for complications during anesthesia if they need to undergo surgery or other procedures. And if a pet already has a health condition, obesity makes the problem that much harder to manage. Being overweight can also lower your pet’s energy level and hamper his or her ability to enjoy an active lifestyle with you and your family.

Even being in the best kennel is stressful for many dogs. If your dog does not tolerate boarding well, consider using a pet sitter or arranging for your dog to stay with a friend or relative while you are traveling. If kenneling your dog is your only option, the following guidelines can help improve your dog’s stay at a kennel.

“Liver disease” is a very general term used to describe several conditions that can damage liver cells. If the problem progresses, it can eventually lead to decreased liver function, liver failure, and death.

Malassezia dermatitis (MD) is a yeast infection of the skin caused by the organism Malassezia pachydermatis. Malassezia pachydermatis is a yeast organism that normally lives in small numbers in the ears and on the skin. The infection occurs when this organism grows in large numbers. In its most severe form, the infection can cause a thickening of the skin (lichenification), making it resemble an elephant’s skin (hence the name pachydermatis).

Medication monitoring can have many components. It can involve testing the levels of a drug in your pet’s blood to ensure that those levels are high enough to be effective, but not too high (which may cause problems or side effects). It may include discussing your pet’s medical history to help ensure that your pet is not experiencing any unwanted side effects from a medication. It may also involve having your veterinarian examine your pet periodically to ensure that the clinical signs associated with the illness being treated are responding appropriately to therapy.

It is recommended that you identify your pet even if you don’t plan to let him or her go outside. Even “indoor” pets can get out by accident, and many lost pets are never returned to their owners because they have no identification. Collars and tags are popular, effective methods of identification, but they can come off. Microchips, which are implanted just under the pet’s skin, are one way to permanently identify pets.

Just like people, dogs can have motion sickness, which can make even short car rides stressful for dogs and their owners. Fortunately, there are ways to ease or eliminate your dog’s motion sickness, including conditioning your dog to car rides and using medications recommended by your veterinarian.

Neutering, also known as castration, is a surgical procedure that involves removal of the testicles. It is a common surgical procedure performed on male dogs and cats to eliminate the ability to impregnate females. Neutering is also used to treat certain medical conditions, such as testicular cancer, anal tumors, and some forms of prostate disease.

Nipping and mouthing are natural, usually nonaggressive behaviors that dogs use to communicate during play and normal interaction with other pets and people. However, most people don’t appreciate nipping and mouthing by dogs, and adult dogs can inadvertently cause injury while nipping and mouthing. Therefore, these behaviors should be discouraged starting in puppyhood.

Currently, studies estimate that approximately half of the pets in the United States are either overweight or obese. The health consequences of obesity in pets include increased risk for joint disease, heart and respiratory problems, and diabetes. Some researchers also have redefined obesity as a chronic inflammatory condition that can have other harmful effects in the body. Being overweight is not cute and it is not just a nuisance; it is now being recognized as a medical problem that should be managed long-term to reduce associated health risks.

During an ophthalmic (eye) exam, a veterinarian may perform a number of tests. These tests can help identify (1) problems with the eyes or (2) underlying diseases that may affect the eyes. Your veterinarian may conduct the exam or recommend that a veterinary ophthalmologist (an eye-care specialist) evaluate your pet.

Most dental disease starts with the accumulation of plaque and tartar on a pet’s teeth. These substances contain bacteria, which can get under the gums and weaken the supporting tissue around the teeth. As a result, abscesses (pus-filled swellings) can form, and teeth may loosen, become painful, or fall out. Bacteria may also enter the bloodstream and infect the heart, kidneys, and liver. A professional veterinary dental cleaning is required to remove plaque and tartar from the teeth and beneath the gum line.

Cardiac arrest means that the heart is not beating and breathing has stopped, resulting in a lack of oxygen and blood throughout the body. If your pet has a cardiac arrest, you may be able to help save his or her life by performing cardiopulmonary resuscitation (CPR), which is sometimes called cardiopulmonary–cerebral resuscitation (CPCR), until help arrives or you can get your pet to your veterinarian. By distributing much-needed oxygen and blood throughout a pet’s body, CPR can help do the work that the lungs and heart have stopped doing.

Pet toys, whether homemade or purchased, can pose hazards to your pet, so it’s important to know what the hazards are and how to avoid them. When possible, supervise your pet while he or she plays with a toy. In addition, help keep your pet safe by following these toy safety tips.

Polyuria (PU) and polydipsia (PD) are the medical terms used to describe excessive urination and excessive drinking, respectively. Because these two abnormalities tend to occur together, the abbreviation PU/PD is commonly used.

Heartworm disease is serious and potentially fatal. It affects dogs, cats, and up to 30 other species of mammals. Heartworm disease has been reported in all 50 states. It is caused by parasitic worms (heartworms) living in the major vessels of the lungs and, occasionally, in the heart. Heartworms are transmitted (as microscopic larvae) through the bite of an infected mosquito. The scientific name for the heartworm parasite is Dirofilaria immitis.

During the birthing and nursing processes, puppies and kittens ingest bacteria that make themselves at home in the intestines. Some of these bacteria are beneficial to the pet, and some are potentially harmful. The beneficial bacteria help digest food, produce energy for the cells lining the digestive tract, and help with immune function. They also help keep the potentially harmful bacteria to a minimum.

Socialization is the learning process through which a puppy becomes accustomed to being near various people, animals, and environments. By exposing puppies to different stimuli in a positive or neutral way, before they can develop a fear of these things, owners can reduce the likelihood of behavior problems in the future and help build a stronger bond between pets and the rest of the family. The critical time to socialize a puppy is during the first 3 to 4 months of its life.

Like children, puppies need to learn the appropriate behavior for living in a household and interacting with others. Puppies also seek positive reinforcement and are willing and able to learn. 

Whether you are deciding to adopt a puppy or an adult dog, there are some things you should consider.

Pyoderma is a bacterial infection of the skin. It can occur when the skin’s natural defenses break down, allowing common skin bacteria to multiply out of control (called overgrowth). Bacteria from another source may also take hold when given the opportunity. Other organisms, such as yeast and fungal organisms, can take advantage of the skin changes that occur with pyoderma and establish their own infections. Dogs and cats of any age can be affected by pyoderma.
