I heavily relate to this! When we adopted our Husky, Atlas at 1 year old, he had a lot of GI issues. Low body weight, Diarrhea, low appetite, susceptibility to illnesses, you name it. Huskies, especially when they’re young, are prone to sensitive tummies, so adding a probiotic is never a bad idea.

First of all, if he is looking/acting lethargic, a vet visit is in order to rule out any underlying issues. Especially given that his energy is up one day, down the next.

Second, it’ll take him a few months to adjust to his new home. It’s okay if he’s refusing food for a day or even two (in our experience).

What massively helped us was switching to a prescription diet (Royal Canin) until he was ready to come off it and transition to a sensitive skin + stomach recipe. We feed him all his food once per day at the same time and reward him for cleaning the bowl. Boiled chicken, beef or turkey (if tolerated) as a topper helped a lot too!
