Brit, look, as of now, SEVEN pages of concerned YTer's. We worry about Jackson just as much as you do! You are NOT a bad pet parent. Things happen many times and it is out of your control. Know that you know Jax is predisposed to this condition you can be an ever BETTER pet parent. When Uni was diagnosed, no she did not have to stay over night, but I did have to bring her back the next day. We didn't know what it was until the bloodwork came back. She had diarrhea for a few days before I brought her in

I should have brought her in at first sign. You are doing the right thing. Sell those bully sticks! LOL.
Just work on getting him better. Worry about treats later. Remember I told you Uni learned all her tricks when she was a puppy solely on kibble? She didn't get any treats until she was about 2 1/2 yrs old. Don't give into the puppy eyes! LOL You guys can do this! You and Jax have an unbreakable bond. He will know what you are doing is what's good for him.
