There are three different sized schnauzer, there is the giant size, the standard and then there is the most popular size the miniature. Their small size is perfect for those who have little to no yard space for their dog. Although their size may be perfect, there are a few diseases their owners should be aware of when living with their schnauzer.
Eye diseases are common for the min schnauzer. There are two different types of genetic disorders they can get in their eyes. One would be retinal dysplasia which is when the retina doesn't always attach correctly to the dog's eye and then there is microphthalmos and this is where the eyes grow far too small to be able to fit properly into their eye sockets.
They aren't actually diseases, but if they have either of these types of disorders they can lead to diseases like glaucoma, PRA or progressive retinal atrophy as well as cataracts. With PRA, the retina of the schnauzer will grow properly when developing in the womb but will then deteriorate as the schnauzer grows older. All of these things can lead a dog to become blind or may even require their eyes to be surgically removed.
There are about 30% of schnauzers that will come down with what is called urinary stone disease or what is called urolithiasis. Vets don't know what makes this happen and why they develop the stones but it could partially be due to genetics. If a dog has diabetes this can cause stones to develop and then the dog will have the need to urinate which will cause pain and blood in the urine.
Other signs they may have this disorder could be vomiting, not wanting to eat and very little energy to do anything. If a schnauzer has this disease he will need his diet changed, special medication and even possible surgery. If this is not taken care of it could get to the point that the urinary tract could be blocked completely.
Another disease that miniature schnauzers are commonly seen with is potential deadly and that is diabetes mellitus. This is where your dog can't process their sugar in their blood properly. Small dogs like schnauzers seem to be more prone to getting what is called hypoglycemia when then can turn into diabetes.
The warning signs that your dog might have the disease is an huge increase in being thirsty, extreme hunger as well as the need to urinate often. Schnauzers can get this as early as when they are two months old.
It is important that you have your dog checked on a regular basis by your vet so that you can make sure that he is taken well care of and so you can make sure he is diagnosed early for any of these problems he is susceptible to.
