Monty the dog has passed the examination! Thanks!

Monty came to the shelter 6 years ago as a very young dog. His family took him away very quickly. He lived as a pet dog for five years, and then something went wrong and he was no longer needed. He was returned to the orphanage. And six months later, when the volunteers came to him for a walk, they saw that one eye had sunk into the socket. Monty was immediately taken to the clinic, but the initial examination did not yield results, the cause was never determined. Now he needs to do an Echo of the heart and check his chest and neck for neoplasms that can have such consequences. Let's help diagnose the dog from Monty's shelter!
