Thanks guys.. Well he definitely is eating the same, we watch during both meals to make sure and have been since we've noticed the loss. His stools are normal but not as much. As far as 10lbs to 5lbs, I could be wrong on that, it just seems like he now weighs what are youngest yorkie girl does. In regards to his age, well that is a mystery. YOu see we adopted him 2 years ago along with another yorkie fellow and the paperwork they gave us was very confusing. One showed him being born in 1995 which would make him 11 and the other showed 1997 which would make him 9. Personally, I'm thinking he is 11 or older. Supposedly, an older women passed away who had 18 dogs and the 2 we adopted were a part of those 18 and all the paperwork was screwed up.
Thanks so much for all your thoughts, I'm so scared to take him to the vet for fear of what they are going to tell me, but I know I've got to do it. I'll hopefully no more Saturday and will keep you up to date. Please keep us in your prayers, I've never owned a pet before and in the last 2 years we've managed to adopt 4 dogs and they are such a big part of our family.
