How many mg's a day of Prednisone does your pup take? I was just curious on how prednisone the pups on here are taking. Toby's been on Prednisone for about 8 years. It started at 5mg a day when he was sick and weaned it all the way down to 2.5mg every other day. Then when he got sick in June again he is back up to 2.5mg everyday. The vet said that he will be taking that much for the rest of his life. |
