9 week old puppy will not eat

I picked up my pup from the breeder last Friday and was given what I was told was the food she has been eating from the breeder.  Pro Plan puppy Savor she wont eat more than 3 bits of it.  I feed her once in the morning and again in the evening she wont eat more than a few kernels.  If I had to guess she has eaten less than a cup of food since I got her.  She Loves treats though and will gobble them up one after another.  I thought It might be the food so I bought Orijin puppy for her she wont eat that either.  Not sure what to do now its obviously not a digestion problem or she would not be eating treats.

I don't just give her treats I start training early in 5 minute sessions. She has two 5 minute sessions a day right now where she gets a total of 10 very tiny half inch sized pieces of treat. I'm going to start using her own Dog food as treats for today's sessions

I think that's a good plan at this point. Each pup is different, but our pup is very food motivated and enjoys when we put his food into the big Kong that releases a few at a time or in the little balls that roll around and drop kibble out. This was mentioned, but I also think it's possible that your pup is just still transitioning to their new home OR maybe they just won't be a big eater. Time will tell. But I think the key is that as long as they are healthy (definitely get a vet check since the pup is new) they will eat when they get hungry enough.
