Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | neutered | 5 months and 29 days old | 10 lbs
My male Chihuahua mix puppy is 6 months old and just had his last series of Lepto, Dapp, and Influenza. He is exactly 10 pounds and healthy. Following his previous shots he has been sleepy and loss of appetite along with pain at sight. But I just noticed blood on his bed, I can't tell if it came from injection site or possibly in his urine. The blood was diluted, a pink color. I couldn't find a trace on his fur. Should I seek medical attention or is this normal after vaccinations?
