For those hot days
Get a kong. place in container/ glass upside down to block the hole on the top. Fill with water and drop some treats inside and freeze it. You now have a puppy popsicle. This is unlike giving ice cubes that break. Give outdoors or some place somewhere you don't mind it melting. Keeps pup busy, a busy puppy stays out of trouble. You may want to tweak this simple idea. Maybe filling with plain yogurt w/ chunk banana, freeze. Get creative.
Kong needs to be the right size, if too small they won't be able to lick inside and if dog is chewer they can take it apart, usually taking the top off.
