When putting shoes on for your dog, please make sure that the entire paw is pushed into the shoe (check by feeling bottom of booties) and tongue of the shoe is not twisted before zipping it up. This allows for maximum comfort. The shoe zipper has to be fully zipped and the velcro should be securely fastened around ankles for proper usage.  Note that if your dog has not worn shoes before, it may take some time to get use to.  We suggest wearing the shoes for about an hour every day for a week to help your dog break into the new booties.  Your dog may walk funny or stand or sit still.  Encourage them to move around and feel more comfortable with wearing shoes.  Your dog should always be supervised and should not be left unattended when wearing shoes.  Please do not put shoes on your dog when paws and ankles are wet or injured or have any other medial conditions.  Do not leave shoes on your dog for long periods of time (more than 5 hours) as the heat may cause discomfort and irritation to your dog.
