Not a problem Nicky - I've moved you to Behaviour
As to whether castration will curb your boy's escapologist tendencies, it may do but don't bank on it. We had a bitch once who was always trying to go walkabout, digging under fences & the like & in her case, it was for the sheer fun of it - she certainly wasn't after any boys
One suggestion would be to try "chemical castration" ie a hormone injection which mimics the effects of neutering & would tell you whether the operation is likely to have the effect you want. This injection generally lasts for around 3 weeks - long enough to see if your boy does calm down & stop his wandering ways. Ask your vet about this - the hormone injection used is called "Tardak"
If you opt for neutering, then possible side effects are a thicker, woollier coat & a tendency to put on weight (though this can be countered by feeding a low calorie diet)
