    Thinks a fun little sniffy toy
    Color: blue, Color: blue
    My puppy seemed curious and didn’t mind playing with this sniffy toy. It’s large and well made and has plenty of title spots to hide stuff. I put kibble in it and my little puppy sniffed and googled a way. I guess this is great for keeping dogs busy and entertained. It’s a pretty cool little way to give dogs treats or snacks.

    Best most adorable dog toy
    So Ivy and Archie got married they are therapy dogs at an assisted living and Jackson was the best man. We fashioned the box with a ribbon around Jackson’s neck but he was too interested in playing with the box for it too last. While the pastor was officiating the wedding the groom did eat the top of the ring off but we snagged it for the bride to wear on her wrist! This dog toy was the best prop ever so adorable well made and authentic! I highly recommend this toy as a prop for a dog wedding !!
