We have two dogs. One can wear a regular cheapy harness from the pet store we got many years ago. She is actually wearing it as a hand me down harness from the other dog as she is a little bigger than the first dog and when we went back to the same store and got the same size/brand they had shortened something on it and it didn't fit the newer, bigger dog right but the next size was too big. I thought the new one was working out well for the slightly smaller older dog, but after wearing it for 4 days while camping (the only time they are in harnesses are when we are camping) she has rubbed a spot raw under her doggie armpit. There is NO WAY this little dog can go up a size in this brand, so now I am looking for more of a comfort harness that won't cause her pain. Any suggestions?
