I have a 4 year old Labrador called Leroy Brown. I get asked all the time what is he mixed with as he is not overweight. He is actually lean and fit and pure breed! (Labradors are prone to being overweight) I simply feed him correctly and exercise him regularly. I find it interesting that the Labrador owners at the dog park ask me this question; I also observe that they are generally overweight too. No wild animals are obese, only domestic ones that are overfed and under exercised like a lot of the population. This is not a rant against overweight, under exercised Labrador owners….. but simply an observation that I wanted to share. Could you imagine if animals were obese?…… we are the only animals that have this problem.
