i would definitly go to the vet with this to make sure it is not a health issue that is keeping him from eating. If it is not.. boy do you have a problem.... ok... can you try putting cheese on it? Layla will eat ANYTHING with cheese on it... what about things like yogurt or cottage cheese... apple sauce.. will he eat that??? does he like treats?? if he doens't like treats i would DEFINITLY be seeing a vet... if he does like treats.. you just have a pup who is playing games with you... there are days when layla is "sick" but she will eat treats.. lol.. i know she is just milking it
what about fish... tuna.... berries... bananas... if you can get him to love ONE Of those things... we might be getting somehwere
but i'd do the vet thing first.... go from there... then you at least know what you are dealing with
Good job with the homecooking.. you pup who eats no problem will really benefit from it!
