My puppy is only 4 months old and he is constantly sticking his penis out, he hasn't been neutered yet and the vet wants to wait till he is 1. Why does he keep sticking it out and what can we do?

There is really nothing you can do about it, it's perfectly normal. i agree with your vet advice, as he is due to be a large breed dog, it's advised to wait until around a year of age for the neutering.

Some dogs can suffer from this problem, where they get an erection and the penis is out and becomes enlarged and then cannot go back into the sheath of the prepuce (the skin that covers the penis). This is called paraphimosis. You can try coating your dog's penis in ky jelly or other similar lubricant and gently pulling the sheath of the prepuce back over the penis. If it is painful and you are unable to get the penis back into the prepuce with this method then a trip to the emergency vet is needed. Coat the penis in lubricant to keep it moist/help prevent trauma. They vet may need to sedate your dog to allow him to relax and then use a dextrose solution to shrink the penis back to a smaller size and replace it. Sometimes a temporary suture will be placed at the end of the prepuce for a few days to prevent the penis from sliding back out before swelling has gone down.

It is likely that he just had an erection. The bilbus glands in the dog are on the sides of the penis and they can become very large during an erection as well. Usually after 15 minutes or so everything will be back to normal. This can still happen even after he is neutered. Best of luck and thank you for using Pet Coach.

This is all quite normal in a young adult dog - if persistent and problematic it may be recommended to neuter him as soon as he is mature enough (at least 80% adult weight; 12-18months for medium-large dogs).
