I guess if you set the study to be for the dogs that have had no known or pre-existing health issues....whether small or on the larger size. I too would like to know. I have a 2lbs 15oz girl and my others are 7 & 8 lbs. All are very healthy thus far, no pre-existing conditions, etc. If a dog has a condition already, I wouldn't think we could use that as comparison. |
