Hi Guys, I just wants some opinions really. My Chihauhau x JR Maximo was hit by a car after legging it out of the front door last September. He dislocated his hip and had to have it put back in pace under sedation. He went back for his check up to see if it had stayed in place later that week and it had popped out again . He then had surgery to put a pin in place to ensure it stayed in place. Maximo is all mended now and being his normal bouncey self. My problem is I have been thinking for a long time about getting Max Castrated as he keeps marking and showing alot of dominance. I feel guilty about putting him hrough another Op if it isnt necessary. He is 3 so is castration going to change his behaviour?, He is a very loving little its mainly the marking that is a problem.
