Our baby is 4 months old....he weighs 3lbs right now....last night we went through something that really scared us. Our baby has been humping since we got him at 2 months...so nothing scary there.....but then we saw his red thing for the first time! The scary thing is that it was huge like 6 - 7 inches, it looked bloody, & it looked like his testicle was coming out, too! We immediately called our vet. He said it is normal in puppies, especially if they are going pretty hard at it (which he was with his loofa dog, like we had never seen before)......he also said if it didn't go down to sprinkle sugar on it, because of the water it in, it would dissolve. Another thing he said was to make sure he peed normally - which he did & it did go down after a few minutes of him calming down. We were so scared, but thankfully he is ok! Has anyone else every experienced this before?
