Im just curious because I do not know if Collies are large breed dogs, I know they can get upwards of 50-60 pounds for males but is this considered Large Breed? I ask because I am currently feeding Lizzie Beneful puppy and yes I know its considered a yuck food but I am going to switch her to Exclusive. Now I know Exclusive isnt as high quality as say Natural Balance or Timberwolf Organics which were my first choices. But I live in Puerto Rico (lived here for 3 years) and there is nothing like that available to me. I can only order them through catalogues and the shipping for a 30 pound bag would be 50-82 dollars So I am feeding Exclusive which is the best thing in my area and I wanted to know if I should get a large breed formula or if a regular puppy formula is fine? Thanks!
