I started noticing that my girls all like to play tug of war together. Except I had no toys big enough for all 3 to play at once. So I went to petco and got one of those tug ropes, the longest one they got!! They love it, they each have room to hold on and pull and they never put it down. Right now Syd and lana each have one end of it and are running around the house bumping into walls with it, they are so funny. If your dogs like to tug i highly recommend this rope, its really sturdy and can withstand 3 strong dogs pulling at it!
I never buy the tug ropes mainly because Oscar has them all over teh living room by the end of the week. He can destroy anything if I let him play with it. But with the lab I used to have he loved the tug toys but he would sling them around so bad he could only play with them outside.
I love rag tugs. There is one toy called a crazy ball, but you will have to buy 3, because they hoard it. They roll it to get cookies to drop out of it. They are pretty indestructable, and the dogs go bonkers over them. I can't leave them outside at night because the dog will 24/7 this toy and it keeps the neighbors up. I used different cookies in it than the stupid ones it came with. Those Livasnaps fit(although they have preservatives, some times I just put cheese nips or like inside.)
