Tye was Castrated yesterday and still recovering from his op, He seems alittle sad

Will give him a few days to settle then we shall get out to the park for some training. Still having problems picking him up indoors. I think it maybe be the way we attempt to lift him. Im new to owning a dog and am finding it hard to know what is the best way to lift a doggie. I have tried the side approach which he seems fine with. But if I try from infront of him with my hands out he backs off. Any advice with this one would be great!

I have been lookiing on the web for videos on picking up a small dog and I cant find anything.
