Looking for any recommendations of play pen brands you like for your puppies. I already have a crate (the same one we use for Diesel which we love). But I want a play pen area for her as well. Are there any brands you have used and loved or vice versa ones you used and hated? Also another question which I have some time to look into. But, do any of you use double leashes for walking two dogs rather than two separate leashes? We never did because Cerberus was so much older and needed to go his own pace. But once our baby is grown up her and Diesel should be at the same energy level and equally capable.
