He looks to be a lovely handsome short haired Golden
One of my favourite colours.
He is a little baby just now so remember lots of peace and quiet and gentle talking while he settles down. Stick with his mix till he is settled too and gradually introduce teeny bits of veg after a week or so of settling.
He will likely be a bit skitty till he gets tame but talk quietly and be calm and gentle and he will soon come round.
He is gorgeous
