Hi! My dog ate a mouse sometime yesterday, and he puked last night, and has puke 3 more times today. He’s really lethargic, and kinda shakey. He’s not as active as he normally is. Should I be worried?

Thanks for using Petco Pet Education Center, formerly Petcoach! I'm sorry to hear Oscar isn't feeling well. I would recommend Oscar be evaluated by a veterinarian; hat is a large number of times that he has vomited, and with him not feeling well, I would recommend he be seen. There is the possibility that he ate something in addition to the mouse; and if the mouse caused such GI upset, he may need some medications to get his GI system normalized. I would recommend he be evaluated by his veterinarian, have any necessary testing done (xrays, etc) and start any treatment that he may need. Good luck!
