My sample packs have just arrived, which I was rather excited about (having heard so many good things about it). Pup has eaten it, but over an extended period, as the kibble is still a bit big for his tiny (but very sharp!) teeth. He's 4 and a half months old. They recommended the utility and agility ones, as they're flatter with a hole in the middle, but still quite big for him. Sometimes there's a lot to be said for having a smaller version for pups ...
How did your small dog get on with it?
Thanks.
