What are the other health benefits of feeding watermelon to my GSD?

Watermelon is 92% water which makes it an ideal snack for your GSD on a hot summer’s day. It can help to maintain hydration, as well as be a refreshing treat that you can both share!

Is watermelon bad for German Shepherds?

Watermelon rind is hard and can have sharp edges once cut so only ever feed your GSD watermelon flesh.

Whilst watermelon is not toxic for German Shepherds, there are certain things you need to know before you offer it up as a snack. As with any treat, moderation is key, and too much watermelon could result in an upset tummy. The high water content means that too much watermelon is likely to give your GSD soft stools or even diarrhea.

A good rule of thumb is to remember that no more than 10% of your dog’s diet should be treats. Even so, this would amount to too much watermelon for your GSD, particularly as it is so rich in vitamins. Bear in mind also that some dogs might be more sensitive to the effects of watermelon than others so always start off by feeding a very small amount of watermelon the first time you give it, just to check that there are no unwanted side effects!

Watermelon rind is hard and can have sharp edges once cut so only ever feed your GSD watermelon flesh. If your GSD wolfs down the rind, he could risk damaging his intestines and he could even get a gastrointestinal blockage.

It’s also sensible to remove the seeds from watermelon flesh before feeding it to your dog as these aren’t digestible and large amounts could cause an intestinal blockage. A few seeds probably won’t do too much harm but it’s still better to be safe than sorry.

How to safely feed watermelon to your German Shepherd

  • Remove the rind
  • Remove the seeds
  • Cut it into small bite-size chunks to prevent it from becoming a choking hazard
  • Only feed small amounts at a time, and don’t give it to your dog every day
  • You could try freezing it for a refreshing treat on a hot summer day
  • Another option is to puree it and let your dog lick it, or mix it with another food

So, can German Shepherds eat watermelon?

Bear in mind that just like people, all dogs are different, and whilst some dogs might go crazy for a piece of watermelon, others might turn their nose up at the offering! If your GSD is partial to watermelon, remember to only ever feed a small amount to prevent an upset stomach. If your German Shepherd does show any unwanted side effects then do not feed him any more watermelon in the future.



How much watermelon can a dog eat a day?
