    You can’t treat the patient if he will not take his medicine

    By Micha on Jun 3, 2021

    Our Vet ordered this medication ( genetic ) in capsule form . No matter how I tried to hide it , doggy always found it and spit it out ! Peanut butter , cheese, steak, the finest deli lunch meat , hot dogs , you name it . Out of desperation I looked for an alternative on line .( my dog is a protective German Shepherd so forcing him to take his pill is not an option . )You get it . I got my Vet to agree to let me try the chewable form instead. He was reluctant , but agreed .Thank goodness it worked . Micha takes it willingly. We will be finished with the treatment in a couple more days !
