What a fun group of hounds you have and so much space for them too!!! I LOVE to see several Bassets living and playing together and we have always had two or three together and they play for ages and being pack animals, they love the company of other Bassets. I often feel sorry when I see a Basset living on his own with no other Bassets to have a rough and tumble with! 15 acres is a massive area for them!!!
