My dog stained the bed while sleeping. Is it blood, pee, or vomit?

Updated on September 23rd, 2025

Pet's info: Dog | Cavalier King Charles Spaniel | Male | neutered | 0 lbs

help. I’m worried for my dog. My dog buddy is about 6 ish years old now. He is a cavalier King Charles and he sleeps in my bed on the opposite side. I found this patch where he sleeps and I can’t decipher whether it’s blood, vomit, pee, etc. And I can’t afford to take him to a vet right now to ask. He doesn’t seem to be acting differently except for eating food slowly which is usual for him as he is very picky and usually does it to pine for our food. Any advice would help me so much :( millie

I would observe Buddy, maybe put a towel in the place where he sleeps. If it happens again, take Buddy to a vet for an exam. Sometimes dogs drool while sleeping or are so relaxed that they pee when asleep. If that only happens once or twice, it is not a problem.
