He did say the problems might not necessarily go away but more likely to help if it's done at the first signs of problems.
As Jack-jack was only 16 wks when he told me about this.. his advice was that i should wait till later seeing he's not got any of the said problems (marking or humping lots..tho he does play with his cushion sometimes

)
It seemed like he didn't think I should just definitely get him done but wait and see...
I wish he could just tell me what to do, it'd be easier
I won't ever use him to breed so he doesn't really need to be entire.. i just feel maybe it's more natural for him to be entire if i can manage him well and he wouldn't need to go through unnecessary surgery.
