COOLING TEETHING TOY. Put the toy in the water, squeeze the top to absorb water through the hollow hole, then place the toy horizontally in the freezer to set. Take it out after 1-2 hours for the pet to lick it to cool down. When the pet plays and bites, the melted ice water will flow out of the stimulation toy, which can quench thirst and provide sufficient cooling fun for teething puppies.
