Other than kibble size, what is the difference? I consider Labs a fairly large breed but Mardi is 37 pounds. I have no idea what her other half is and she isn't a puppy. So--do I feed her large or small breed kibble?
It really is mostly hype, marketing. Some will say that there are some ingredients that are geared to certain breeds, but it is certainly not a requirement. Labs are actually a medium breed, not large. Large would be Great Dane, etc. Is Mardi a Lab mix? Sorry I don't know your story, what are you currently feeding? If she is doing well on what you are feeding (no ear or skin infections, coat looks good, firm poops and not excessive amounts, no vomiting, etc) then keep her on what you are feeding now.
Mardi is a newly adopted, 2 year old, 37 pound Lab mix. She is tiny and thin and I would like her to gain a few pounds. Since I got her she had 2 weeks of terrible diarrhea and ended up eating Hill's ID. That helped and I have just completed switching her to Canidae Lamb and Rice. I don't think she is completely digestiong this food and will probably try something else in a few weeks. She is OK at present and I don't want to switch her to another food so soon after having both ID and Canidae being new to her. I am about to call my vet and ask her to draw blood and send it off to Spectrum Labs for food allergy testing. I had two previous rescues allergy tested and the results were helpful. I have no idea what else is in Mardi except for Lab. She looks like a black Lab puppy but is really about 2. The other half must be some tiny breed.
as with any food you want to know the calcium levels. i would not feed a food with a calcium level higher than 1.2 and certainly not to a puppy.
as the others have said, labs are not large breed dogs, therefore don't really need a lb food. it is a marketing gimmick.
