Lost my walking buddy today.

My walking buddy is gone and the family is shattered. He was 11 and hardly sick day in his life. 3 weeks ago he started having stomach issues. Got some prednisone and it started eating and being playful again. He still loved his daily walk. Just yesterday we had a good walk and he was hungry, eating well and drinking good. Suddenly in the night was puking. Go to vet and they give him an antibiotics and nausea shot. 4 hours later he dies in my lap. I am not sure the point of this post honestly. I just felt the need to say something to others not my family. We moved here 12 years ago with my daughter going into first grade. She just started college away from home and this happens. I feel so bad for her. Max had a good long life with lots of love. Don’t just know what to do now other than feel lost. Thanks for listening.
