dog feet

Thanks for all the replys, soundin good so far. I myself have noticed that the cat footed dogs are a little more agile at a younger age. I was just wonderin if the loose footed dogs, feet breakdown at an earlier age, or cause the dogs to slow down any earlier. Some that i have seen look like they are walking with all their weight heels, just seemed to me, that the joints wouldnt be properly cushioned, and cause ther joint to break down. and its not just curs, I have seen alot of hounds with feet that looked so bad, i couldnt see how they could run at all.
keep em comin, i hadnt really thought about those flat footed dogs, being good for swamps, that does make sense. I could see how a flat footed dog could go a little better in the water than a cat footed dog.
