i just found it on his wee-wee pad & it's the 1st time it's happened...he's a 6 month old, neutered male bichon frise puppy (paddington)...he's been acting totally fine today & tonight, so i don't know what's up...we got back from his weekly puppy play group 2 hours ago & he had a blast...should i rush him to the ER tonight or can he be seen by his regular vet tomorrow (?)...he's not showing any signs of distress & i don't know what to do :s:wondering
