Thank you for using Petco Pet Education Center, formerly Petcoach. If Dobby hasn't eaten in 2 days he needs to go back to the veterinarian ASAP. He may have a more serious infection such as parvovirus or could have a GI obstruction. At his age he needs immediate intervention to recover. Puppies this young can become hypoglycemic and dehydrated very quickly if not eating. Please take Dobby to a vet asap for further evaluation.

    I am sorry to hear that Dobby isn’t feeling well. This is highly concerning for an intestinal obstruction. I would encourage you to have him seen by a veterinarian immediately. An x-Ray, blood work, and possibly a barium series may be needed. If there is an obstruction then surgery will be recommended. Best of luck and I hope he improves soon. Thank you for using Pet Coach.

    Since it's been 48 hours, I would recommend a vet visit at this point. He may just have some inflammation in his gut and need some supportive care (anti-nausea medication and fluids under his skin) or could have something more serious going on like parvo virus. If he's so tired that he's not able to get up and walk around, I'd recommend going to an emergency clinic tonight, otherwise it should be ok to wait until the morning. Good luck!
