    Hi Again,

    I have posted several times over the last few weeks concerning a skin infection that my 10 year old female cocker spaniel has has...

    Got the test results today...and she has Hypothyroidism...She is a very sleepy girl and sleeps really soundly with her eyes closed really tightly..she is also very cold...I usually have to wear a sweater on her or cover her with her blanket...she gained some weight also..

    My question to anyone who has dealt with this is....How long until her medication starts to work???? That is the one thing I forgot to ask her vet when she called...I have picked up her medication and started her on it tonight...

    My vet gave me some information but it does not say how long till the medication starts to work and also what changes should I look for to make sure the medication is working...She has an appoimntment in a month for bloodwork.

    Any Information will be very useful since I have never dealt with this...

    Thank You

    Usually about a week and she should start perking up noticably, I know personally being hypothyroid I can tell day by day whether or not i need to up my dosage and I can def. tell if Ive missed a pill.

    Thanks so much....I can't honestly remember a time when she was really peppy....I look forward to her feeling better...

    It has been a long hard road finding out what was wrong with her. I hope that we are finally going in the right direction...

    Thanks Again

    Every dog responds a little differently, but there are gradual changes beginning in a few days. Some owners report dramatic changes. Most feel the changes come more gradually, but when they think back over the month, the dog really is acting a lot different. You have enough changes (sleepy, weight gain, cold) that I think you will see deffinite changes, even in a few weeks.
