I haven't posted in a long time, but I think what has happened with my girl Cecil should be shared. For the pastnine months Cecil has been gaining weight. I Put her on a diet about three months ago and she did not loose weight. A friend of mine with 2 Norweigen Elk Hounds told me that this happened to one of her girls who was much older. Cecil will be 4 in August. It was hypothroid. Weight gain and high chloresteral. When put on a diet, no loss. I took Cecil to the vet for a wellness checkup yesterday and told her to run thyroid tests. Today the results came back. She has hypothroidism. Now she must take 2 pills a day for 30 days and then 1a day for the rest of her life. She will lose weight. My vet told me to forget the weight management things we had discussed and feed her as usual. This is not life threatening except for some Golden Retreivers. Please, if your beagle is gaining weight for no appearant reason and not losing it on less food, losing hair more than usual, or drinking more water, somewhat of a couch potato when in the past not so....get him or her checked out. Specifically ask for the check on the thyroid. I feel better now and I hope this helps at least one person.
