After shaving a golden retriever, it will usually grow back in about 3 months. However, the hair growth rate of different individual dogs is different, which is mainly affected by the dog's body constitution. Therefore, after the dog's hair is shaved, parents can appropriately prepare some high-protein and other nutritious foods. You can also choose some seaweed powder, hair-beautifying powder and other nutrients. Feeding them in appropriate amounts is also very good for dog hair growth.
