Some Small Breed Health Issues

While Chihuahuas have fewer genetic defects than many breeds (due to many breeders trying so hard to eliminate problems), no breed is perfect. The following sections show you some idiosyncrasies, a few serious but most not, that are sometimes seen in Chihuahuas and other Toy breeds.

Subluxation of the patella

Subluxation of the patella or loose kneecaps. When it occurs, the kneecap (the rear legs) slips out of its groove, sometimes often and sometimes rarely, depending on the severity of the problem. If your dog is one of the unlucky few whose kneecaps slip often, surgery may be the solution. A dog with a mild case can live a normal life, kind of like a person with a trick knee. Subluxation of the patella is a relatively common problem in small breeds and some large breeds


Hypoglycemia means low blood sugar and is a common problem in young Toy breed puppies. Symptoms of low blood sugar are a staggering gait, glassy eyes, and sometimes either limpness or rigidity. If the dog doesn't receive immediate help, he can suffer seizures, unconsciousness, and finally, death. Treatment involves putting some sugar in your dog's mouth, calling your veterinarian, and heading for the clinic. Once you know your dog has a tendency toward hypoglycemia, you can prevent further attacks by changing his feeding schedule to small amounts several times a day and avoiding sugary treats (check the ingredients before buying dog treats). Just remember, too much sugar in itís food can put your puppy on a roller coaster ride of sugar highs and lows rather than keeping his blood sugar nice and level.

Try this little trick: If you get your Puppy used to taking delicious liquid from an eyedropper, administering liquid medication becomes a cinch. Occasionally melt a teaspoon of vanilla ice cream, put it in an eyedropper and give it to her just as if it was medicine. puppies for sale, health issues of small breed dogs or puppies, teacup Chihuahuas, Molera, Heart murmur, anesthesia, modern gas anesthetics, Collapsing trachea, Hypoglycemia, Poms, Yorkies, teacup Poms

Collapsing trachea:

Collapsing trachea is a problem for Toy dogs of many breeds. The symptoms include coughing, shortness of breath, and exhaustion. Although it appears more often in dogs older than 5 years, an occasional puppy has it from birth.

To understand the condition, think of the trachea as a straw made of cartilage that carries air from the neck to the chest. When the cartilage collapses, breathing becomes difficult, kind of like sipping soda through a flattened straw.Your vet can treat most conditions with medication.

Heart murmur

Heart murmurs are relatively uncommon in Chihuahuas and even those that have one usually have the functional type. As in people, they can be as active and athletic as they want and live long, normal lives. Most puppies do out grow it.


Mainly in Chihuahua may displayed or have a "soft spot" on top of there head. In the Chihuahua, this spot, or fontanel, is known as a MOLERA; and is the same as that found in human babies. In the past, this molera was accepted as a mark of purity in the breed, and it is still mentioned in most Chihuahua breed standards the world over. AKC standards say: A well rounded "apple dome" skull, with or without molera.

It is important to note that while many Chihuahua puppies are born without the molera, there are probably just as many born with one and its presence is nothing to become alarmed over. Some times it may close up

Unfortunately, many lay people and many veterinarians not familiar with the Chihuahua have tried to link the presence of a molera with the condition known as hydrocephalus. This has caused many newcomers to the breed serious concern and worry. The truth is that a domed head with a molera present does not predispose the Chihuahua to this condition. 

While it would be impossible to list all the medical documentation here on this page, these few included here are perfectly clear; the presence of a molera does not mean the Chihuahua has a medical problem.

The Chihuahua is a little dog! They belong in the house, at their owner's side, receiving all the love they deserve to receive. With or without a molera, the healthy Chihuahua that is loved and given proper veterinary care will live well into its teens as an irresistible member of the familyHydrocephalus

Going under anesthesia

The possibility that your dog may someday need anesthesia is one main reason why you need to choose a veterinarian who is accomplished in treating Toy dogs. Although anesthesia-related deaths are rare, and usually the result of an allergic reaction, its use is potentially dangerous. Your vet uses anesthesia only when necessary (before surgery, for example).

Be sure you know how to clean your puppies teeth properly so that cleaning them under anesthesia isn't necessary. When your dog has to go under anesthesia (during spaying or neutering, for example), ask your veterinarian if any necessary dental work (such as pulling impacted baby teeth) can be done at the same time.

Be sure your vet uses one of the modern gas anesthetics. They are much safer than the old fashioned intravenous products. Never do anything that anesthesia is used, that is not necessary to save your puppies life. Before you risk your puppies life, ask yourself is it really necessary.

Watch those eyes

It's certainly not a condition, but because Chihuahuas have big eyes and live close to the floor, they are more prone to eye injuries than a lot of other breeds. Put several drops of saline solution in your dog's eye if the injury seems minor. That's often all it takes to flush out a foreign object that was accidentally kicked up by someone's shoe. If that doesn't relieve the problem, or if the injury appears more serious, take your puppy to the vet.  puppies for sale, health issues of small breed dogs or puppies, teacup Chihuahuas, Molera, Heart murmur, anesthesia, modern gas anesthetics, Collapsing trachea, Hypoglycemia, Poms, Yorkies, teacup Poms
