Sorry to hear about your loss, unfortunately I think i'm going to have to put my black lab down soon. Probably within the next couple days, he's been doing circles in the house and in the yard and cannot walk straight. Took him to the vet and they can't figure it out, without having an mri, or catscan done, and unfortunately being unemployed don't exactly have the money for that kind of thing. I think it may be a brain tumor an old neighbor of mine had a lab get a brain tumor and this is exactly what it did. He's only 6 1/2 years old, great hunting partner.
