Thank you for using Petco Pet Education Center, formerly Petcoach! It does sound like Milo is acting a little strange. This can be caused by pain, discomfort, or nausea. I recommend keeping a close eye on him over the next 24 hours and having him seen by a vet if these symptoms continue. He should be seen as soon as possible if he begins vomiting, has diarrhea, loses his appetite, or is unresponsive. I hope this helps and am happy to answer any other questions you may have!

    I would see if there is an ER vet close to you, as it's very concerning that Milo is vomiting as well as not eating or drinking anything, and breathing funny. This is not something that can wait until Monday, he could quickly get sicker and/or become severely dehydrated from vomiting and not having any water. If there isn't an ER vet in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website site. Please start calling around to find a vet to see Milo now. Best of luck.

    Hi there! Sometimes dogs have days where they just don't feel right, just like we do. As long as he isn't vomiting, having diarrhea, or is unresponsive, it's probably safe to just watch him for a little while and see what he does. Additionally, if he doesn't appear interested in food, this may also be an indicator of something brewing. I recommend that you bring him to the vet if he hasn't perked up within 24 hours, or if any of the symptoms I mentioned above develop. Good luck and I hope that Milo feels better soon!

    Hi. It sounds like Milo is pretty sick. If he is sleeping a lot, not eating, and vomiting, he needs to be seen in order to find out what is going on. Since he is young and only 6 months old, if he is not fully vaccinated Parvo is definitely a possibility. He could have also eaten something that he shouldn't have. Parasites are also a possibility at this age as well. He is most likely sleeping a lot because he is lethargic and not feeling well. I would recommend getting him seen right away so that you can get on top of whatever is causing this and get him some supportive care no matter what the cause is. Good luck and I hope he feels better soon
