my 3 month old pug loves to pee in her kennnel

I got her from a place wehre she was kept in a playpen and just went where ever she wanted and whenever. I take her outside a lot, and those times when she doesn't go outside, which is all the time, I will take her and put her in the kennel for 5 -10 minutes and try again. as soon as i put her in the kennel she will pee in it. I have had her 3 weeks and I am very frustrated. I know I read pugs are hard to potty train, but why her sleeping area. I have been giving her a bed in there, but she will pee on the bed and sleep on it. we go outside more than we should to be honest, probably every 15 or so minutes. She will sometimes go outside but more often than not she will hold it and pee in her kennel. Any tips on getting her to stop peeing in the kennel and pee outside.
