I loved watching Emergency Vets because I learned so much. Best of all, when my blue merle long-haired Dachshund/Australian Shepherd mix, Chelsea, suddenly began urinating in the house, I was able to realize she was exhibiting signs of having bladder stones. My vet confirmed my suspicions & Chelsea had an operation to remove them. In fact there were so many stones in her bladder, it was no wonder she'd begun having "accidents" in the house. The vet gave me most of the stones - they others were sent off to be analyzed & oh, how they stunk!
Later on when I found a fatty tumor had developed on the front of Chelsea's chest, I insisted it be removed - mostly because of where it was located. Neither my vet nor I suspected it was anything other than a fatty tumor; but, I'd agreed to have it sent off to be analyzed and we were both shocked to learn they found cancer in the very center of the tumor. Apparently, like an oyster creates a pearl when a grain of sand creates an irritated place inside it's shell, Chelsea's body reacted by creating a fatty tumor to encapsulate the cancer, Just goes to show, not all fatty tumors are not a cause for concern.
Thank you Emergency Vets for teaching me to be observant & take my pet into see a vet whenever something just doesn't seem right - when my pet's behavior has suddenly changed even subtlety.
