Hip dysplasia is terrible. 8yo Aussie having more trouble daily with slick surfaces- ceramic tile, wood floor, laminent-you name it. JUST applied first application to back paws and his reaction was priceless to witness. It you’ve got the extra 5 minutes to trim hair around the pads, then you’ve got 5 more minutes each paw to apply the treatment. 40 minutes to a happy, more confident pup while helping him prevent injury = priceless!
