It's more of a challenge to keep a blind dog safely active. Our first dog went blind very young (retinitis pigmentosa at 3 yrs) and she had a hard time keeping weight off. It's not like she could just run pell-mell through the yard.
Awwww I saw this on the new and it broke my heart. I know that my female, Lexus is blind and I am not sure how she will survive without her mate Bimmer. I can tell you that she was never food aggressive till she lost her vision. Now there is no way we would let any children or other pets (other than Bimmer) around her while she eats. She is gluttonous with it also. I guess just making sure she gets it while she found it. Maybe she thinks she will never find her way back to the bowl.
