Training & BehaviorWhy is my dog sad and not eating after we adopted another dog?
Thanks for using Petco Pet Education Center, formerly Petcoach! This could certainly be due to the change in the household with a new pet. However, this should subside relatively quickly. If Ollie has not improved in the next 2-3 days, have him evaluated by your veterinarian for further assessment to make sure there is nothing else more concerning going on. In the meantime, you can try to entyce his appetite with things like chicken or ham. Good luck and have a great day!
