hi my 2  year old staff is skinny compeared to my other 2 he is 15 inch tall and has a fairly big head but he has no weight behind him!!! he is the most fussy eating dog ive ever came across, he refuses to eat dry food (even thow all 3 of my dogs have been on this all there lives!) he will only eat meat  or tuna, or pasta & corned beef! but when he eats this he dosent eat the next day like its filled him up for a week !!!  and he looks  like i dont feed him
he also is the most scared dog ever he crawls around like as if hes in the army!!!!!, jumps at the slightest sound and crys (well screams) if hes in the the garden at night! help me please as i feel so sorry for him ! what can i do!

I'd look into getting a vet referral to a good behaviourist. If he's so scared, you need help -and being constantly stressed will make it much harder to put weight on as well. You also do need to insist on him eating the one food you want him to eat and not offer anything else.

ive tryed not giving him anythink at all but then he just starves himself! and just picks one or two peices out the bowl a day! some times he will not even bother at all!! as for the scared bit , the vets have told me  that i should keep putting him in the garden at night and sit with him so he learns that theres nothing out there that can harm him, and when iam there he just sits there like he s not scared to be there! when in the house if i get up pretty quick he jumps up and sort of ducks down  but then realizes its nothin and lies back down again!!
