Chicken backs causing sores on the gums.....

Two possibilities I can think of, other than just "getting used to" the exercise of chewing.

1. He had some scale/tartar to take off under the gums and now it's healing up.
2. The chicken is irritating his gums, ie, he's developing a sensitivity to chicken. That's a really weird way for that to show up, though, in a dog.

Cool ok.

Guess I was more worried about the bones actually poking the gums.

He's had beef knuckle bones since he was a tiny puppy, but he has been overly excited by the fact that he can actually have MEAT and the bone!

Thanks Brookcove!

After further inspection of our fenced in acre lot. It's not the chicken backs at all, or doubtful I should say....this big oof, as we've nicknamed him, has been chewing on the buttom edge of wire gauge fencing in a section of the yard.

Will have to reinforce/replace that section, least he didn't massively destroy the fence or his mouth. My guess is he's trying to play with the rabbits and or the fox that comes up to the back of the yard and just lies there staring at him.

At least I know what it is now that's causing the sores, cause today, they were a lot worse, and I was really starting to wonder about him chewing bones.

Obviously it's not the bones at all; but I will put him back on ground turkey and veggies for a few days, let his mouth heal up.
