Why is my unneutered male dog humping, not eating, and throwing up?

Updated On September 23rd, 2025

Pet's info: Dog | Cardigan Welsh Corgi | Male | unneutered | 1 year old | 33 lbs

My unneutered male dog won't eat around my spayed female dog and tries to hump her even though she's spayed so obviously can't be in heat. When he does eat, he throws up.

Thank you for submitting your question regarding Chubbs. He needs to see his veterinarian if he is not able to keep any food down. He could have an intestinal infection, a dietary intolerance or even be experiencing an intestinal obstruction from ingesting a foreign object. This last case is very serious and requires prompt treatment. In the meantime, you can try keeping him separate from your female dog to allow him to rest. I hope this information helps!
