castrated st bernard

Question
should my male castrated st bernard be locking onto my female st bernard who is in season ?

Answer
Hi Chris

Depends on how he was neutered.

Castration is the removal of both testicles.  When a male is castrated after sexual maturity, his sex drive may be normal even though  he is unable to impregnate a female.  Very  

Bilateral vasectomy is sterilization whereby a segment of the right and left vas deferens (the tubes that carry the sperm) are removed.  Vasectomized dogs have normal sexual responses and can breed and mate with a female but is not fertile.

So yeah, it's common.
