Thank you everybody so much! I appreciate all the info. I had some vanilla Breyer's all natural and gave my guy a taste of that... boy does he seem to think that's a great treat! Obviously, though I don't want that to be the only thing I do. I'm going to follow up with our vet on getting a draw for the full thyroid panel at hemopet once next pay check comes through. You were right he was only checked for T4. Thank again basenji forums!
I was looking back at pics from when he was younger and weighed more. I think he's always been a bit taller than standard and had a little barrel chest. Used to call him a basenji bouncer at the dog park. He was all about playing with the labs, pits and other big dogs - probably because he knew he could outrun them if they ever got too rough. He's much more about slow walks with me and lap snuggles these days ❤
