Okay please don't misunderstand me. I have never seen your dog, I prefer my dogs thin and have never had a fat dog. That being said for discussion sake: aging dogs: I say this with delicate words umm okay, my Sierra is my oldest aussie she is 14 1/2. Gus is my oldest male at 12. Both of them feel bonier (no such word I know) to me. Sierra who has been 41lbs her entire life, is 36lbs now. Gus who was 62lbs his entire life is 57-58lbs (he did have some colitis, surgery and few other problems this year, lost 10lbs was very ill and never gained it all back.) Gus doesn't look skinny (and he has that aussie show coat so one has to feel to see) but he feels like an older dog, boney...I can't explain it but I can feel it. Most dogs over 10 start to change and you can certainly feel a difference. I have a 10 almost 11 year old aussie girl. She is 42lbs, always has been. However the other day when grooming I thought her hips felt a tiny bit sharper, not skinny just more pronounced. I exercise my dogs a great deal, Gus not as much this years, Sierra no more as she is wobbly but Ginger gets tons but I still feel changes. Sooooo I'm not saying your dear sweet loving gorgeous dog is skinny but if the dog is getting up there in age 11-13 you said he could actually feel more uh sharp, his muscle may not be as tight so you can feel the bone in a more pronounced manner. Or maybe he is skinny and frankly that is healthy! Emaciated is not healthy but on the skinny side is good.
People always say my Ginger, the 42lber is skinny and well I'd say yes she is and I like it that way. I expect her life will be longer and healthier because of it
