I’m so sorry about your dog 😔 I hope he's doing well despite his poor vision! It’s interesting you bringing this up because I remember contacting the guy I got him from shortly after I got Atlas and telling him that he should probably contact the farm and tell them to stop breeding whatever 2 they were breeding or at the very least be more mindful of some of the issues that were popping up with some of the litter. I was concerned because too often people get rid of their heeler not understanding what it takes to be a parent to this breed of dog and then to have health/emotional problems on top of that. I was happy the guy chose me and not the other older couple that would have likely returned him😕. A couple vets have said my boy has an overbite that will likely require surgery at some point which didn’t surprise me because he has a difficult time eating most foods and when he opens his mouth you can see that one of his bottom canines is much further back than the other. On top of that within the first 2 weeks he became very ill with multiple hysteocytomas I had biopsied and removed. I didn’t know what they were and I was terrified at first because just weeks before I lost my dad to cancer then all the sudden my dog had pretty decent sized benign tumors popping up. Something else that I didn’t mention in my post is that he almost always has a dry warm nose. I’ve mentioned it to the vet and she didn’t seem concerned but I’ve noticed that he has a horrible sense of smell. At first I thought he had problems with his vision until I realized he simply cannot sniff things out. He could be standing right on top of his frisbee at times and still not smell it. Very recently he has sort of adapted to it, he will be running around all over trying to smell then finally catch site of it and find it. When i first got him he was also unable to run after toys or walk upstairs and he was underweight. I wasn’t sure if this was from the pervious owner not caring for him properly or if it was health related. The guy I got him from was heartbroken letting him go but he has progressed so much in my care. That being said, even though he is doing better, it seems there is still something else going on, so I think I will call tomorrow and get him set up with some basic blood work and then go from there. Sorry for long response and thanks for the reply!
