My dog is suddenly blind and destructively chewing everything. Why?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Male | neutered | 11 years and 11 months old | 60 lbs

We have a 10 to 1 year old Yellow Lab /Chow mix (mostly Yellow Lab). In the last two weeks he has been going blind (bumping into walls and legs). At the same time he started new behaviors of climbing counters, tables and other places to eat/chew on anything that even had touched food (like empty cardboard, wrappers and such). Last night he destroyed some Christmas presents that didn't even smell like food (like pot holders and socks). Any advice?

If you are noticing a sudden onset of blindness, Ryder needs to be examined by the veterinarian right away. This could be an indication of high blood pressure or other system disease that may respond well to treatment if caught early. A sudden change in behavior could be behavioral in nature OR it could be related to increased hunger from an endocrine disease. Discuss this with the veterinarian as well and make sure to keep things up and out of Ryder's reach. I hope this helps.
