Prior to the Science Diet i/d they were on what the breeder we got them from had them on which was Purina Puppy or something like that. I had planned to switch them after they were a year (which they just turned a year on Saturday, August 2nd

) but had to sooner due to the gastro problem Roxie had. The vet did run tests and they both have been back since and all is well now. Now when we board them and upon returning home, we are careful not to let them (especially Roxie) gorge herself and feed them slowly.
