I dont know why, but Maggie stinks. Kizzy has never smelled like that altho both of them do smell like outside dogs when they first come in from playing outside if its kinda hot out especially. But I can give them both a bath. I dont smell kizzy even a week later except the outside I was saying. But Maggie gets a bath with the exact same thing, the exact same procedure and soon as she dries, to me , she stinks. But its not like just a yard dog smell. you know how it smells in some kennels where they have a lot of new puppies and lay around together and people dont keep it clean? (I suppose like maybe a puppy mill maybe, not sure or a pet store smell thats not clean). But anyway thats what she always smells like lately. She is kept clean but if some days I dont spray her down with cowboy magic detangle and brush her, she simply stinks most days. Seems like its gotten worse since she got older to me. She didnt stink when I got her other than a puppy smell that wasnt bad or strong. Anybody got any idea why she would smell like that? I dont think its the food because I've changed their food at least 5 times since I got her plus they both eat the same thing. They eat science diet lamb and rice for now. I mean she dont stink all the time when she stays in the house but this smell isnt just yard dog. I leave them out when its pretty for maybe 30 minutes to and hour off and on during the day as they love it outside. Kizzy comes in and smells like dirt or yard dog for a few minutes. it goes away after she gets in where its A/C. Maggie just has a total different smell and I dont know how to describe it. She goes to the vet tomorrow and I will ask them what it could be but someone here might have some ideas. would yall please answer this asap if you have any idea? I'd sure be thankful.
