Sorry to hear winter was so tough. It's not always easy for the seniors we love.
My old man, Hondo, will be 30 this year. He is like Pepper as far as the teeth goes. He gets some soaked alfalfa cubes & beet pulp in a mash w/senior feed & corn oil. He also gets free choice Timothy/Orchard. I put the fresh hay in a metal drum and have a go at it with the weed whacker & chop it. If there are any heavy stems, I pull them out before I chop.
Life is like a camera. Focus on what's important, Capture the good times, Develop from the negatives and if things don't work out, Take another shot.
