Frequently asked
Are watermelon seeds toxic to dogs?
Not chemically toxic, but they are a real intestinal-blockage risk, especially for small dogs. Always remove seeds, or pick seedless watermelon.
Can dogs eat watermelon rind?
No. The rind is tough to digest and is one of the most common causes of GI blockage when dogs raid the fruit bowl. Remove all rind before serving.
How much watermelon can I give my dog?
A medium dog can have ¼ cup of cubed watermelon as an occasional treat. Too much causes loose stools because of the high water content.
Can puppies eat watermelon?
Yes, from about 8 weeks. Start with one small cube and watch for stomach upset.
Is watermelon juice safe for dogs?
Fresh, unsweetened watermelon juice in tiny amounts is fine, but the fresh fruit is better (fibre + natural chewing). Commercial juices often have added sugar.
