I just got home and I noticed something wierd about my 13 year old rottweiler/german shepherd chow. I looked at his eyes and the pupil of his right eye was completely red, It almost looks like his eye is bleeding from the inside. His other eye is a little bit red but very faintly. It doesnt seem like he is in any pain. I think he could probably be blind because he doesnt notice much anymore unless you make a noise. heres another problem... In this past month and a half, he has gotten extremely skinny. I can see his ribs and where the rib cage ends, it goes right in. The poor old guy is just skin and bones. He drinks TONS of water lately but doesnt eat alot. His arthritis is also getting to him. A few nights ago we heard some cootes barking and yelping. We have a friend who rents out trailer and the noises were coming right from underneath his window. He looked out and saw 4 coyotes circling something. He didnt know what it was and went back to bed. In the morning, we realized they were probably circling rocky. I have also noticed coyotes in our back field watching him. I yell at them but they just look at me, they dont even flinch. it is sort of scary how they are getting so used to humans. Ever since, we have been keeping rocky in the garage and tieing him up at night on our porch. does anybody know what could be wrong? We are taking him to the vet on thursday. We are waiting for the vet to call us back. I hope he is ok!
