A．
Summer comes and we start thinking of ways to increase liquid intake. Water-rich fruits like watermelon become a basic part of your diet during summer. These fruits can certainly help to stop our thirst. Watermelons are not only nutritious but also help us beat the summer heat. However, can watermelons be shared with our pet dog?
There is absolutely no harm in giving a watermelon to your pet. Watermelons are excellent sources of vitamins A and C as well as minerals. Moreover, they help to stop your pet’s thirst as they contain more than 70% water.
Before sharing a watermelon with your dog, make sure that you do not feed beyond his ability to digest. The amount you feed will vary depending upon how big your dog is. For instance, if you have a small breed dog, giving a small slice is enough. However, an adult Golden Retriever certainly has the ability to consume more slices.
Also, make sure that you remove the seeds before feeding watermelon slices to your dog. This is because dogs find the seeds very difficult to digest; hence their consumption is likely to cause stomach upset. Moreover, the seeds can actually be harmful to your dog as the seeds can be poisonous to your dog when eaten too much. Even taking a few may cause stomach upset in some dogs. So it is best to avoid feeding the seeds to your pet.
As far as offering the skin of the watermelon is concerned, you should avoid it. While the rind(外皮) contains a great number of nutrients, if not chewed properly and swallowed, it can get stuck in the stomach and cause a serious digestive problem in dogs.
On the whole , while watermelon is not bad for a dog’s health, feeding it in small portions without the skin and the seeds is necessary to keep digestive issues at bay.
