There are lots of good recipes you can find online by typing in…how to make homemade dog biscuits…below is one really good one.

when its hot like this dogs love ice cubes so if you can find a plastic container fill it half fool of water and then add things ur dog likes to eat like biscuts or other items you have and freeze it for a few hours once its hard your dog will eat the ice to get to the treat and cool off, a small caution if they get bored with it pick it up quick it will leave a big puddle

For an entire list you can go to this site

Our fur baby girls LOVES cheese! She has her own bag of bite sized pieces of sharp cheddar, colby jack & provolone in the fridge most of the time. She also loves ice, so I especially like the “hide a treat” idea. Will try it today!
