Teddi is 17 weeks old...she is quite difficult to feed...At the moment i am trying puppy Science Plan, she will eat about an egg cup full and thats it....She doesnt seem to like Orijen puppy either...She loves chicken, liver, and roast beef but walks away from most other things.....Should i l leave her with the dry food...i get concerned if she goes without food for any long period... Any suggestions please?...
