While I usually split large and small dogs into different play sessions, many times they all get along and play beautifully. It takes a while to learn the dog's personalities and to match the play sessions. Twenty five years of teaching dog training with a play session component has given me lots of experience choosing appropriate play groups. And boy, do they have fun!!!!! Thanks to Jag, Lola, Sadie, Sookie, Koko, Bruiser, Paris, Greta and Betty for being such good sports!!
