My 14 yr. Old black lab is having a horrible time with kidney leakage. She weighs app. 100 lbs and yesterday we gave her apple cider vinegar but wasn't sure how much to give. I gave her app. 1 1/2 tablespoons and diluted with a little water ... She has been gagging since we gave her the ACV. What should I do????? I don't know if I should give her anymore of the ACV because she's still gagging and nothing comes up. She has plenty of water to drink ... But she only drinks when she wants to. How much and how can I give her the ACV? PLEASE ... I NEED HELP!! I DON'T WANT TO LOSE MY BIG GIRL ... I KNOW IT'S INEVITABLE WE ALL HAVE TO DIE BUT I DON'T THINK I CAN MENTALLY HANDLE IT AT THIS POINT IN MY LIFE. ANYONE WITH MORE INFORMATION ... PLEASE ... PLEASE LET ME KNOW ASAP. Sincerely needing help.
