The picture with plastic bottle just cracked me up - that's one of Venom's favorites, too. Only he prefers the 2 liter bottles. One of his favorite toys is a car tire - really. He carries it to the top of a small hill, watches it roll down, starts all over again. Good exercise! His other favorite is an 8" lavender colored berber bear from PetEdge. He's 6, has gone thru 3 in his lifetime. They're tough! He wants to carry it when we go for walks. 110 lbs of doberman, 8" lavendar bear. Strikes me as funny when we're out walking, Venom carrying his teddy bear, and some people are still scared and cross the street when they see him.
