Max wants a friend to play

Max is 7 months old, but his size says something else. He is 3 ft tall and weighs about 70 lbs. My little great Pyreenes puppy has grown in size but still a baby. Max is in dire need of a friend to play with. Although there are Roo and Dumdum, Max can't entice them to play with him. They do entertain Max from time to time, but Max's size and roudiness as well playfulness put them off. From time to time Dumdum lets Max ride on his back, but not for long as Max is much bigger and heavier than Dumdum. Roo lets Max pull her tail and her ears, but Max sometimes gets carried away. So, most time they tried to keep away from Max. Max rolls over, crawls on his belly just to invite them to play with him, but they ignore him. Poor Max. Max tried to find other friends to play with him. He goes into the woods and brings home a tortoise. Plays with the tortoise but it was no fun since the tortoise does not respond. He tosses up the tortoise, catches it up in the air, kicks it, but there isn't any response.
Yesterday Max found another friend to play with. It was a baby bird learning to fly with mother bird flying around to encourge its baby. Max was excited, he went to pick up the baby bird in his big jaw and tossed it to fly. He chased it around the yard and catched it again and toss it up. Mama bird was worried and made a lot of noise, but Max was enjoying himself and perhaps the baby bird was enjoying it too. After a while when Max tossed the baby bird a little too high, the baby bird landed on the branch and stayed there. Max was heartbroken and tried to jump to get to his new friend, but the mama bird was encouraging the baby bird to get back into the nest. Aall afternoon, Max sat under the tree waiting for his new friend to come out to play.
Poor Max needs a friend to play.
