Hi Ronnie, Just wanted again to thank you for all your help with fitting Haley with her new booties!! Haley got to go on her first walk with her new shoes last night, and did just fine.. Actually she doesn’t drag her rear feet with her new shoes on… Strange but what ever works! She loves them, and trots her whole walk these days, she is a happy Lab!The M+ size did the trick. Again thank you for your super service! Best Regards, Mary Best to all and again your customer service was super! Mary Arnold, Broker
