I had my cross dog castrated at 6-7 months. He was not lifting his leg then.
A couple of months ago, aged 18months, he started lifting his leg occasionally. Now he does it most of the time when he pees, he also still tries to hump other dogs when playing with them, but not the children or the cushions anymore.
Is it possible that the castration was incomplete?

Castration is not a cure-all.  It won't stop a dog lifting his leg or humping other dogs.  I doubt it's anything to do with the op.

Castration - as you're currently learning - neither guarantees to prevent nor cure ordinary male behaviours :)  The only things guaranteed by castration are that your dog will not develop testicular cancer - because his testes have been removed and of course very few entire males actually go on to develop that disease anyway - and that he will no longer be able to sire progeny.

He is behaving as he does now because he is a juvenile male - not because his castration is "incomplete".  Leg lifting to urinate is associated with scent marking (one of my bitches does it too :rolleyes: ) - humping, whether other dogs or objects, can be deterred by training and appropriately socialising and will almost certainly be put a stop to (or fiercely objected to) by other dogs so work on distraction techniques now before he finds himself at the receiving end of a disgruntled mature male ;)

My crossbred male dog was castrated at 5 months of age. He started cocking his leg and mating bitches at 3 years of age. It just took him a bit longer to get the idea!

Bramble was castrated at about 2 1/2 ish. He certainly knew what to do when Tara came into season for the first time 3 years later :D :D :D

It has nothing to do with the castration, my bitch humps boy dogs, but my castrated boy doesn't, thats just a behaviour that some dogs have and others don't.
Castration will help cure hormonal driven humping not behavioural, also hormonal aggression, not behavioural.  It will also stop testicular cancer later in life.

The only bitches that Bramble has ever humped have been in season :) :) :)
