Summarize this article in one sentence.
Since the gums are soft, it's easy to scrape them and make them bleed. Unfortunately, this can be a serious injury for a pup with low platelets. Until the vet tells you your dog is in the clear, stick to a well-balanced soft dog food. Your dog needs to rest until it starts to feel better. Additionally, a lower activity level helps protect your dog from accidental injury. Since even a slight bump can cause bruising, it's hazardous for your dog to be too active. Encourage your dog to lay on a soft blanket or pet bed while it recovers. Talk to your vet before returning your dog to its normal activity level. It's important that your dog not get injured while its platelet counts are low, as its blood won't clot well. Unfortunately, even a small bump or scrape can become life threatening to a dog with low platelets. To protect your dog, go through your home to make sure you don't have any potential hazards. For example, don't leave items lying on the floor, make sure items on shelves are secure, and check that doors and cabinets are fully open or shut. Also, it may help to put padding on sharp furniture corners, if you have any. Your dog is most vulnerable when it's outside or around other animals. That's because it's easy to come across something on a walk that could injure your dog, like a stray branch or a hole in the ground. Similarly, it's impossible to predict how animals will act. Be very careful while your dog is in recovery. If you can, keep your dog away from other animals, and try to walk it in an area you know well.
Switch your dog to nutritious soft food, which is easier on its gums. Reduce your dog's activity level to help it recover. Remove any items from your dog's environment that could cause injury. Supervise your dog closely while on walks or around other animals.
