Viruses and Parasites – UGH!
(And what you must do to protect your Pet)
One thing you can count on in this great nation of ours is an argument. Doesn’t matter what the subject is, there’s somebody on the other side. Vaccinations are one of the most hotly debated health issues we have when it comes to child care and it’s no different when it comes to our pets. They are one of the most misunderstood weapons in our healthcare arsenal. Before you make up your mind one way or the other, here are some facts to consider about a host of things you must either protect your pet against or understand the treatment options if your pet is infected.
Highly contagious and deadly, Canine Parvovirus is one virus you do not want to deal with. It is the number one reason that we are total clean freaks at both Barks and Recreation and Barks and Medication. Unfortunately, the vast majority of dog owners are unaware of how many different ways their dog can come in contact with this deadly virus. It is easily spread by dog-to-dog contact- at the dog park or on a walk, contact with contaminated feces, food and water bowls and once infected you can expect vomiting, severe diarrhea, loss of appetite, abdominal pain and lethargy. If your dog displays any of these symptoms, contact your vet immediately. The parvovirus can kill in as little as 48 hours. Puppies under 4 months of age and unvaccinated dogs are most at risk.
food bowls, another excellent reason you should not leave your pets water and food bowls outside overnight
Lyme disease is transmitted primarily by a very small tick with black legs (one way of identifying them) called a deer tick. Another way of identifying them is that the lower half of their back is red or red-orange while the lower half of the backs of almost all other ticks is black or very dark brown. Not saying you should ignore other tick bites- they can all transmit disease, but if you remove an imbedded, smaller than average, black-legged tick with a red lower back, save it and take it to your doctor when you go to be checked for Lyme disease. Lyme disease is a nasty illness that can cause serious, recurring health problems for both you
and your dog. It is important to note that Lyme disease vaccination is not available for people and not indicated for all dogs. In many cases, the vaccination may present more risks that benefits. Your dog’s lifestyle and the area of the country in which you live, or spend time in, can be large factors in the decision. You need to trust your veterinarian on this one.
Every year, the annual influenza epidemics have up to 20% of the population sniffling, aching, coughing, and running high fevers. You read and hear about H1N1, or H3N2, two sub type combinations that routinely cause people to “have the flu”. The “H” and “N” stand for proteins on the surface of the virus. There are 18 different H sub types and 11 different N sub types and that makes possible almost 200 basic combinations. Dog Flu is highly contagious and almost 100% of dogs exposed to it will become infected. Over 80% develop flu- like illness not unlike those experienced by people. The mortality rate is less than 10% but that is a frightening number when you consider how contagious this virus is.
Enteric means having to do with the intestines. You’ve seen “Enteric Coated Aspirin” for example. That is aspirin coated with a material that allows the aspirin to pass thru the stomach before it is released in the small intestines. Canine Enteric Coronaviruses attach to cells in the victims small intestine and result in diarrhea and painful abdominal cramping. Puppies seem to be the most at-risk along with dogs who live in crowded, unsanitary conditions. The virus is easily spread by contact with infected fecal matter, eating or drinking from contaminated bowls, or direct contact with an infected animal.
You probably haven’t heard of Bordetellosis, but you probably have heard of “Kennel Cough”. While most cases of kennel cough are caused by the bordetella bacterium, kennel cough has become a catch-all name for a group of symptoms that can be caused by a number of other bacteria or conditions. It’s like you ask for a Kleenex, someone gives you a Puffs, but it’s OK- you just wanted a tissue. An effective vaccine is available and is required at most training, boarding and day care facilities. If your dog develops a consistent cough for any reason, see your vet- and use a harness instead of a collar. Pulling against a collar can easily aggravate the cough or cause damage to an already irritated trachea.
Adenovirus 1 (CAV-1) causes Infectious Canine Hepatitis which can cause liver damage and death, while Adenovirus 2 (CAV-2) generally causes relatively mild respiratory illness. CAV-1 is one of the viruses vaccinated against when your puppy gets its first set of shots, the DHPP round, for Distemper, Hepatitis, ParaInfluenza and Parvo. But because the vaccine made for CAV-1 can cause many side-effects, the vaccine made for CAV-2, which causes far less side-effects, is used for both. That works because both viruses are able to confer cross-protection, meaning that when your dog’s immune system produces antibodies against either one, they work against the other as well. CAV-2 can be spread very easily thru animal to animal contact, or thru exposure to saliva, feces, urine or respiratory secretions from an infected canine. I say canine because any of the 36 member species, including foxes, wolves and jackals can contract and spread CAV-1 and CAV-2.
CANINE PARAINFLUENZA is a respiratory virus and one of the many viruses that can cause kennel cough in dogs. It is highly contagious and commonly develops in situations where a lot of dogs are in close proximity to each other. Although the symptoms may resemble those of Canine Influenza, they are unrelated viruses and require very different vaccines. Anytime the phrase “where a lot of dogs are in close proximity to each other” is used, you automatically think of Boarding and Day Care facilities- and that is a great example. But other large risk factors have to be considered: shelters, rescue centers, breeding kennels, pet stores, groomers, dog parks and show events or competitions. Vaccination against parainfluenza is normally included with the vaccines given for Bordetella.
INTESTINAL WORMS are parasites and are fairly common among pets. Some are much more dangerous than others. Most of these common parasites are contracted by ingesting infected soil, water, bodily waste, or an infected host such as a bird or rodent. Once your vet has determined the type(s) of worms your pet has, it’s fairly simple to control the situation. Hookworms, Roundworms, Tapeworms and Whipworms are generally the most common. Medicines given vary depending on the specific type of parasite and the level of infection. Owners often decide to administer de-wormers on their own, without understanding that
many parasites, including tapeworms, are not curable with over the counter treatments. Symptoms include diarrhea, bloody stools, pale tongue and gums, itching around the anus or the obvious visible worms in your dog’s stools. Some heartworm preventatives, like Sentinel Spectrum, come with the added benefit of preventing all four of the most common worm parasites. Roundworms and tapeworms can cause serious problems for humans and require immediate attention. Roundworms can infect lungs as well as the intestines causing a variety of symptoms including coughing, shortness of breath, nausea, vomiting or
diarrhea. Tapeworms will not develop into adults in human hosts, but tapeworm larvae can produce cysts in the lungs, liver or brain leading to serious illness.
Doesn’t even sound good, does it? Another intestinal monster, but this one is super small microscopically small and causes BIG problems. A single-celled organism called a protozoan, these parasites can be found in the large and small intestine and they can cause bloody diarrhea, which left untreated can cause dehydration and death. Puppies and dogs with compromised immune systems are the most likely to show symptoms. Once the dogs develops a mature immune system- generally by six months of age, its body may keep Coccidia under control and may ultimately clear the infection on its own.
Giardia is another protozoan parasite that in many ways is like the Coccidia protozoan parasite just described. Giardia rarely causes severe symptoms while Coccidia is very capable of causing enough intestinal damage and dehydration to require hospitalization. Only your vet can tell the difference between the two infections and prescribe the appropriate (and different) treatments. There are no vaccines available for Giardia or Coccidia and monthly medications for control of other parasites are not effective. Both are very treatable and hygiene is the key to preventing both. Tests for both should definitely be included in your dog’s yearly exam.
If you have questions about anything in this article, consult your veterinarian. As stated in the article, many of descriptions of how viruses or diseases affect you or your pet were extremely over-simplified, as much for the sake of space as anything else.
If you have questions about whether or not you should take the time, or go to the expense, needed to protect your dog from all of these conditions or infections, just ask yourself if you would like to have any of them personally.
