Giardia In Dogs

There are still many things that veterinarians don’t know about giardia and infections in dogs.  Giardia are actually protozoans — single celled organisms.  It’s not uncommon for them to be in the intestines of many animals, including dogs.  However, we don’t know just how common giardia is.

Giardia is a parasite.  It attaches itself to the lining of the intestine.  It can also float free along the lining of the intestine.  Some dogs are asymptotic — that is they never show any symptoms.  Other dogs will develop symptoms related to a giardia infection.  And we don’t know why that is either.

Giardia is usually most dangerous for puppies.  The infection can manifest itself as diarrhea and bloody or mucousy stool.  Other symptoms associated with giardia include weight loss, listlessness and poor appetite.

A puppy or dog may have a long-term, low grade giardia infection and, when he become stressed for some reason the infection can flare up and become very serious.  This means that giardia can linger for a long time.

Giardia exists in two stages:  the swimming, feeding stage in your dog’s intestine and the cyst stage that passes through his feces and which is deposited on the ground.  These cysts can survive for several months outside the body if there is enough moisture present.  If your dog ingests them again, or if another dog ingests them, then the cycle begins all over.  This makes giardia very hard to get rid of once it’s on your property.

It’s always important to pick up after your dogs but it’s especially so if you suspect that one of your dogs has a giardia infection.  This will help prevent your dog, or one of your other dogs, from becoming infected with the organism.

It is suspected that giardia may also be passed to humans.

If your dog is experiencing ongoing problems with diarrhea, especially if there is bloody or mucousy stool, you should see your vet.  Your vet can confirm a diagnosis of giardia by checking your dog’s stool for signs of the giardia cysts.  Cysts are only passed occasionally so your vet may need to do 2-3 fecal exams to find evidence of the giardia infection.

If your dog does have giardia then your vet will probably treat the infection with metronidazole or quinacrine.  These are the two anti-protozoal drugs most often recommended for dealing with a giardia infection.

Puppies are most at risk of becoming dehydrated from the diarrhea associated with giardia.  However, with good veterinary care your puppy or dog should recover from this infection.  If you have other dogs it’s a good idea for all of them to be treated whether they are showing symptoms of giardia or not.  You will also need to thoroughly rake up even the smallest traces of fecal matter from your property so your dogs can’t become re-infected.

It’s very important to prevent your dogs from sampling manure samples from other animals, including cows and horses.  Many animals may carry strains of giardia and your dog may pick them up when he noses around in them.

Although this is the course of action when giardia can be determined, there are many times when your dog may have diarrhea and the cause is unknown.  Your vet may be unable to make a definite diagnosis.  Giardia may be suspected but your vet may be unable to confirm it.  In cases like these you should follow your vet’s best advice.  He may decide to treat your dog for a bacterial infection or not treat the diarrhea at all.  As long as your dog improves, that’s what really matters.

How Do Dogs Get Tapeworms?

Worms aren’t a very pleasant topic but they are something that you should know about if you have a dog.  You may hear about different kinds of worms and wonder how your dog can get them.  How does your dog get tapeworms, for instance?

Dogs get tapeworms from eating fleas.  Fleas ingest tapeworm eggs and when your dog eats the fleas he eats the tapeworm eggs, too.  They then happily hatch out inside your dog.  A single tapeworm can grow to be four to six inches long in your dog’s intestine.  The tapeworm’s head attaches to the intestine.  As it grows it is followed by many little linked segments.  These little segments look like rice.  They break off and your dog passes them when he uses the bathroom.  You can sometimes see them in his stool or they can catch on the fur around his rectum.  A single tapeworm may have 90 of these segments.  Each of these segments contains more eggs for the tapeworm.

When you take your dog to the vet (and this is one reason why you should take your dog for an annual check-up), your vet can identify these little white links as tapeworm segments.  Sometimes these links will show up in a fecal exam, but there is no guarantee that a tapeworm will conveniently break off when your dog is at the vet so your vet may not find the segments when he does the fecal exam.

Over-the-counter wormers for dogs do not work on tapeworms.  You will need a prescription wormer from your vet to kill the tapeworms.

A tapeworm can infect your dog for a year or more.  They rob your dog of the nutrients that pass through his digestive system.  Your dog may have abdominal discomfort, he may be nervous, and he may vomit.  If you notice these signs in your dog, even if you don’t see the rice-like segments of the tapeworm around your dog’s tail or in his stool, take your dog to the vet and tell him that you suspect your dog may have tapeworms.

Tapeworms can be passed to humans so it’s very important to kills these parasites as quickly as possible.  Beefing up your flea control will help prevent tapeworm infestations from getting started.  If your dog has had tapeworms you will also need to treat your yard and home.

If you have a puppy, most vets will offer worming when your puppy has his series of puppy shots.  Make sure that you get this worming for your puppy since it will take care of any tapeworms that your puppy may have when you first get him.

There are other worms and parasites that can bother your dog but most of them can be killed by over-the-counter wormers for dogs, with the exception of heartworms.  Make sure that you get your dog tested annually for worms with a fecal exam to find out if he has any worms or parasites.  Your vet can answer any questions you have about parasites and your dog.
