I love making my dogs treats, especially when they are easy to make. And my dogs love anything that has the word “treat” in it.
I don’t think there is an easier treat to make than these frozen watermelon dog treats unless you count plain ice cubes (which my dogs do).

Is Watermelon Safe for Dogs
According to the AKC, watermelon is safe for dogs as long as you make sure to only give them the flesh of the watermelon. The seeds could cause an intestinal blockage and the rind can cause an upset stomach leading to vomiting and diarrhea.
Watermelon is also low in calories and high in water content and nutrients, which makes it a great treat for dogs.
Just make sure not to give your dog too much as too much can lead to stomach upset due to the high fiber content of watermelon. Also, even a low-calorie treat can add up to too many calories when given in large quantities.
Frozen Watermelon Dog Treats
Always consult your veterinarian before giving your dog new foods.
To make these easy frozen watermelon dog treats you need only two ingredients, seedless watermelon and water.
Cut the watermelon into smallish pieces and put about 2 cups worth in a food processor or blender.
Add 1 cup of water.
Blend until it is mostly slushy.

Then pour into ice cube trays, I like these cute bone and paw-shaped molds, that are on a cookie sheet or other tray.
I use the cookie sheet to help catch any spills, especially in the process of moving them from the counter to the freezer.
Place the filled trays flat in the freezer and let freeze for at least 3 hours. Depending on your freezer it may take longer.
Once they are frozen remove them from the tray and store them in a freezer-safe container. I use freezer bags like these.

Tips for Making Watermelon Dog Treats
If you make these in small ice cube trays, like these paw and bone-shaped trays, you can give your dog multiple treats instead of just one larger-sized treat.
My dogs care more about the number of treats than they do the size, so why not let them think they are getting more than they really are?
These treats can be sticky, so they are best given outside. They also seem to thaw quickly so it is best to give them soon after taking them out of the freezer.

Would adding a banana & decreasing the water make these treats not melt so quickly?
I haven’t tried it but I know decreasing the water by itself won’t help. I originally made these with no water, just pureed watermelon, and they seemed to melt even quicker. Adding the banana may help but without trying it, I can’t say for sure.
