I found my dog in the backyard with a dead mouse in it's mouth. Do I need to do anything like get her some medication or take her to a vet? She is 8 months old and up to date on all of her shots.

There are some diseases that can be transmitted from a mouse to a dog, but it's not that common. Dogs eat rodents and birds all the time and rarely have any problems. I would just make sure that she received a leptospirosis vaccine and that she gets a dewormed in the next month or two. Otherwise, she should be fine. If she shows any signs of illness, then it would be worth a visit to the vet, but it's not necessary to rush to the vet anytime soon. I hope that helps and all is well with Bella.

    In general, mice do not carry the diseases that we vaccinate for. The exception is that they can shed Leptospirosis in their urine, so I would be sure to mention that to your veterinarian when you are discussing which vaccinations are appropriate for Kai. The other thing to be concerned about is if there is any possibility that the mouse had eaten any rat poisoning. If Kai has any vomiting, loss of appetite, or lethargy, be sure to have your veterinarian examine him right away to be safe. Good luck! I hope that was helpful.

    Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear that Lily got into a dead mouse. More than likely she will be ok but whenever dogs or cats ingest strange or odd things like this, there is always potential for intestinal and stomach upset to occur. I would watch for nausea, drooling, vomiting, and/or diarrhea. If any of these signs develop and they persist, I would advise having your vet evaluate her and treat her for dietary indiscretion. She may need drugs for vomiting/nausea and/or diarrhea. Good luck with Lily. I hope nothing comes of it.
