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.

Acetaminophen is the active ingredient in Tylenol and some other related medications that are used to treat pain and fever in people. Unfortunately, this drug can be extremely toxic (poisonous) to cats and dogs. Acetaminophen toxicity occurs when a cat or dog swallows enough of the drug to cause damaging effects in the body.

While the estimates vary, approximately three to four million dogs and cats are euthanized (“put to sleep”) each year in the United States because too few people spay or neuter the pets they have, too few adopt their new pets, and too many give up their pets. Because space at shelters is limited, staff members must make the difficult decision to euthanize healthy animals that aren’t adopted within a certain amount of time.

Dog agility is a competitive sport in which a person (handler) directs a dog through a timed obstacle course. Handlers and dogs race against the clock as the dogs jump hurdles, climb ramps, run through tunnels, cross a see-saw, and weave through a line of poles. Scoring is based on faults, similar to equestrian show jumping. Dog agility competition has become an exciting spectator event, and training for it is a great form of exercise for dogs and handlers, can harness a dog’s energy and boost his or her confidence, and can help improve the human–animal bond.

Alkaline phosphatase (ALKP) is an enzyme that is produced by many cell types. Although it is considered a “liver enzyme,” it is mostly made by the liver and bones.

Anal sacs are a set of glands that are just under the skin near your pet’s anus. The two glands arelocated at the 4:00 and 8:00 o’clock positions from the anus. The anal sacs fill with a foul-smelling fluid that is normally expressed through a tiny duct when animals defecate. Animals may use their anal glands to mark territory or repell aggressors, although a nervous dog or cat may accidentally express these glands when frightened.

Aspirin has been considered a safe and reliable over-the-counter fever and pain medication for decades. Because aspirin is considered very safe, some pet owners give aspirin to their pets. There are also aspirin formulations specifically for dogs. However, high doses of aspirin can be dangerous for dogs and even more hazardous for cats. Aspirin toxicosis occurs when a cat or dog swallows enough of the drug to cause damaging effects in the body.

Some animals may have several of these clinical signs, whereas others may have only one—perhaps an ear infection.

While dogs have been domesticated by people for a long time, it is important to remember that they are still animals with a very strong instinct for “fight or flight” when danger is present. When presented with a threat, many dogs will try to escape; however, some dogs will choose to fight against the danger and may bite in response to the threat. It is important to follow certain safety guidelines when working with dogs to avoid injury for you and your dog. Remember, an adult large breed dog may weigh as much as a person, and all sizes of dogs have sharp teeth that can easily injure a person with minimal effort. In fact, small breed dogs weighing less than 25 pounds are more likely to bite than larger breed dogs.

Barking is one of several types of vocal communication by dogs. You may appreciate your dog’s barking when it signals that someone is at your door or that your dog needs something. However, dogs sometimes bark excessively or at inappropriate times. Because barking serves many purposes, determine why your dog is doing it before attempting to address a barking problem. Does your dog use barking to get what he or she wants? For example, dogs that get attention for barking often learn to bark for food, play, and walks as well. Therefore, training your dog to be quiet on command is important so that you can teach your dog a different behavior (such as “sit” or “down”) for getting what he or she wants. Dogs of certain breeds and dogs that aren’t spayed or neutered may bark more than other dogs; therefore, it can be more difficult to reduce barking in these dogs.

Bladder and kidney stones are hardened accumulations of minerals found in urine. Common minerals involved include struvite, calcium oxalate, and urate. Dogs and cats can develop stones anywhere in the urinary tract. Stones can form in many different shapes and sizes.

Bringing a new kitten home is exciting. These guidelines will help you and your kitten adjust to this big change in your lives.

Periodontal (gum) disease can lead to tooth loss and affects most dogs before they are 3 years old. Bacteria from periodontal disease can spread to affect other organs and cause illness. One of the best ways to help prevent periodontal disease is to brush your dog’s teeth on a regular basis—daily, if he or she will allow it.

Many conditions in dogs require medicine to be applied to the skin. 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 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.

Kidney disease is a very general term used to describe any one of several conditions that can affect the kidneys or damage kidney cells. If kidney disease progresses, it can eventually lead to kidney failure and death.

Our pets share so much of our lives that many of us don’t want to consider traveling without them. Whether you are flying, driving a car, or RVing, sharing a trip with a pet can add richness to the experience. Proper planning can make the travel experience better and less stressful for you and for your pet.
