Your dog will try to shred and chew on the blankets. So, the animal blankets should be safe so that the small fibres do not cause a blockage in their stomach. Blankets that have loose threading, or if the thread of the blankets comes out when the pet uses its claws, such blankets might not be safe to give to your dog. But in the case of fleece blankets, they are harder for dogs to shred. Neither do fleece blankets have fibres that come off. Moreover, the fabric is very soft and warm for the pet. So, yes, fleece blankets are a hundred per cent safe for dogs. And the best brands you can rely on our Furhaven, Scruffs, Trixie, Buddyrest, and many more.
