In order to choose the right size of dog boots for your furry mate, follow the below steps to correctly measure the paw size: 1. Put your dog's paw on a piece of paper and gently press the paw down. This will spread the paw on paper and will just like when your dog actually walks. 2. With a pen mark the left and right side of the paw on the paper 3. Measure the marked distance with the help of a measuring tape 4. Similarly, take the measurement of the back of your dog’s paw. It is important to measure both front and back paws because some dogs have different paw sizes. 5. After you have completed measuring the paw sizes, add about 0.2 inches to the measurement to be on a safer side so that you do not end up buying a tight pair that makes your dog uncomfortable. It will give your dog’s feet some room to breathe and spread its toes.
