My botfriend and I have resently bought us a cocker spaniel puppy,I'm the one home with him all day and night we have 4kids 3 boys and 1 daughter! The puppy is now 15 weeks,when during the day he won't eat unless I hand feed him!! What should I do??

You have made it harder by actually hand feeding him (don't worry I am guilty of doing it as well!)

Are you feeding the same thing the breeder was feeding? Or have you changed the food?

I just got a new puppy and I started feeding what the breeder was giving him and he didn't seem that interested. I bought a different food that I know my older dogs like and he went crazy for it!

I would play around with the food a little to find something your pup likes, it might take a few tries but not all dogs like the same food.
Just remember to change foods slowly if you do decide to try it to avoid an upset stomach
