We do this often because our dog is a Malamute mix and has TONS OF HAIR!! What we brush off his fur could fill a 100 bird’s nests for sure! Since we do not have fleas or ticks where we live in the mountains, his fur is pristine and fluffy— perfect to keep any bird’s nest comfy and warm!
We used an empty orange bag to put his fur in so the birds could pull out what they need and it worked great!!
