Amazing and cute
Size: Small, Color: Pink, Size: Small, Color: Pink
I have a puppy who absolutely adores her toys, especially now that she’s teething! I picked out some pink ones that are just right for her—she’s only 2 1/2 months old and weighs 2 lbs. The best part is the variety of toys she loves to play with.
