Oh, dear, I have a terrible experience with that, too. About 6 years ago, when I was fresh out of college, I was roommates with a lady who bought an English bulldog puppy shortly after I moved into a duplex with her. This sweet, if slightly gross, boy dog wore a harness for most of his first year. One day, I came home from work for lunch to find him moving a little more slowly than normal. I noticed that something in the house smelled a little painty, a little wrong, and I worried that maybe the dog was ill (I had been spending a lot of evenings at my dog fosterer friend's house, where she'd had a sick dog whose breath smelled kind of like that). But when I smelled my roommate's dog's breath, it just smelled like dog food. I decided to wait for my roommate to get home and ask her if she'd noticed anything. She came home a short time later, and we searched the house for the source of the odor. We realized as he lumbered toward us from her bedroom that it wasn't so much the house that smelled as it was... him. But it wasn't his breath. She bent down and loosened his harness, and the smell became overpowering. She ran to the sink and threw up while I took the harness off the rest of the way to find an oozing wound on his chest that had either been caused or exacerbated by use of a harness that was always worn and probably seldom checked. We both felt horrible. She threw away the harness and rushed him to the vet. He rebounded quickly, but my friend took care to only put a collar on him when she was taking him somewhere, and I only put it on him for his walks.Quote:I have seen what long term collar wear can do to a dogs neck. I won't let that happen to my two.
