However, giving squash to dogs isn’t entirely without its risks. Here are some downsides:  

• Too much can cause digestive upset. While squash contains helpful fiber, too much of it can lead to gas, bloating, constipation, or diarrhea, especially if introduced suddenly. Start slow and watch for any signs of discomfort. 

• Some parts may be hard to digest. The skin and seeds of many types of squash, including butternut, acorn, or spaghetti squash, can be difficult for dogs to digest and may lead to stomach upset. Remove the seeds and peel the skin before serving.
