My dog,Derby is sick these days.It didn't eat any food 3 days ago.Every day I can only feed it with water.And it seems too tired to get up.I was very worry about it so I sent it to the vet yesterday.The vet looked over it and gave me some medicine.I hope few days later it will bark happily again. 这只是我的愚见,希望能帮助到您,
