my boxer puppy

Question
I just went through the struggle of my 8 year old female boxer dying of a brain tumor.  I healed as much as possible for 6 months then decided I was ready for another puppy.  I now have a three month old boxer boy and am watching every move because of my last experience.  He has only had one testicle drop and I am worried about how to spot signs in personality if cancer exists.  I could just be over worried.  Are there warning signs?

Answer
Hi Erik,

You're over worried :)  

That said, he should be seen by the vet.  Most vets will neuter a dog with an undescended testicle by 7 months of age if the testicle cannot be manipulated into the scrotum.  

If he is not neutered, and the testicle remains in the groin or abdomen, as the case may be, his chances of developing cancer are great.

If your vet can feel the testicle just above the scrotal sac, he may choose to wait a few months to see if it drops on his own and have you come back in for a check-up.  If the testicle cannot be felt, he may opt to neuter sooner.

Some dogs maintain a testicle as high up as into the abdomen above the penis.  If this is the case, the dog may have to have what we nickname a 'speuter'.  A normal neutering incision and then an additional incision near the navel (in the same area as a spay incision) to reach the testicle.

Your vet will be able to advise you better :)

Please don't be too worried.  While it's not desirable, the condition is common and easily corrected.  A dog with an undescended testicle should not be bred from and cannot be shown.  Just FYI.
