Dog shoes designed for dogs that need the rugged protection of a rubber sole. Hiking, running on the beach, snow, ice, hot pavement, protection from thorns, or grip on slippery floors. Be sure to try on all four shoes. Take care to not snag a dew claw, and wrap the velcro snugly around the leg. For the introduction and always check each shoe by tugging on the end before setting them free! This will ensure you have fit each boot snug and secure. Dogs will always walk funny for the first few minutes and usually adapt very quickly to the sensation of wearing shoes. Have your camera ready! If the dog only wears one boot it will likely refuse to walk, please try on all four and you will have a much better result. These shoes are appropriate in summer or winter conditions. Moisture can enter from the top of the shoe but will give some protection of cold and prevent snow from sticking between the toes. Sizing- Put your dogs foot on a white piece of paper with weight on the foot. Draw a line at the widest part of the foot on opposite sides. Carefully measure the distance between the lines. The distance should be between 1.4 inches and 3 inches. Choose the size that is closest and above your measurement. i.e. if you measure 2.3″ choose the Size 6 shoe that is size 2.5 inches. Size 1 = 1.4″, 2 = 1.6″, 3 = 1.8″, 4 = 2.0″, 5 = 2.2″, 6 = 2.5″, 7 = 2.8″, and 8 = 3.0″ Please write to us if you have any questions.
