This has been my mom's go-to toy to gift to friends and family when they get a new dog. I just followed suit and bought one as a gift for my friend's Newfoundland puppy. Versatile, can be used as a ball or tug of war toy, and can buy a bigger size for a puppy to grow into because they can still grab it by the holes, unlike other balls and toys that are just too big to get their mouth around

I love this glow oil! It is not too messy, leaves a beautiful, glimmery sheen and has SPF! I use it on my face, chest, arms, and feet!
