So I've been posting about a food for my lab/shepherd puppy and now I'm wondering about a large breed formula. When did you all start your puppy on a large breed formula? My boy is 4 months and approximately 20 pounds. I was told by a vet (that I no longer use) to wait a few months to see how he grows to determine if large breed formula is necessary since he may only top out around 60 pounds. I've never had a large dog so I'm not sure if this is necessary at all. Since I'm having such difficulty finding a food he really likes, I'm wondering if I should be taking this into consideration right now as well. I don't want to find a food he really likes and then have to switch it again. I just started him on simply nourish yesterday (mixing with totw) and he seemed to like it but they don't have a large puppy food. Any suggestions for me? Thanks!!
