Our boy aged 2 and 3/4years,has been castrated  approx 2 months ago.
Against our initial plans but he bit the vet, and he said "I strongly recommend you have this dog castrated".
Anyway he had to undergo a GA for a grass seed and so we said well do it at the same time then.
His behaviour is not particularly different, except that in the evenings he likes to curl up alongside us on the settee, before finally being removed to the kitchen, to sleep in own bed when the last person goes to bed.
This boy seems to object more and more, he growls and snarls then looks contrite and all is okay. Last night though my OH just moved his position on said settee and he was growled at........
Any thoughts or advice?

Don't allow him the privilege of being on the settee, he is seeing it as his right not a privilege, he is abusing it so stop it.

Thank you, that was quick!
I guess it may be firmly back to basics then.

The fact of having him castrated will not make a difference to his biting the vet one way or the other but it is possible he has been allowed too may privileges since he was done and now thinks he can do what ever he likes.

There right you know, Whistler snarled at me once when I touched his food bowl. Only once, he got put in his place at once, they try it on. I do allow Whistler on my lap occasionally but his place like Jake is on the floor!

I suppose that is the trouble with little dogs!
So easy to encourage the wrong behaviour.............now the consequences 

Still sorry we agreed to castrate.......

Unfortunately, and contrary to a lot of vets advice, castration isn't the answer to all the problems that dogs present with.  It's only successful if the problem behaviour is as a result of the testosterone levels (high) which are then reduced as a result of surgery.

Another things to bear in mind is, that if castration is effective, it can take a few months for the benefits to show.
