4 - Despite your title - dog doesn't look too 'happy'. Like to have seen the focus sharper on the dog's eyes and the blown areas on the balls/baubles reduced. The black fabric so much in focus at the fore is slightly distracting. edit:typo
Here he is...he's so cute! Great job with the black surroundings that really makes the picture stand out. I like this shot - like the addition of the green and red - adds character. Good detail. Overall good shot!
