Sometimes my dogs seem to need a little shampoo between shampoos. A lot of times, really. I hate to bathe them overmuch, but on a farm they can get into so many things and end up stinking rather quickly. I've bought Fabric freshener that 's made for pet odors to spray on my carpet occasionally and I've even been tempted to try that, but I'm pretty sure it wouldn't be healthy. There must be something, though. Any suggestions?
