Hi everyone, My dog Mylo has suddenly started gagging and seems to be choking on something. But, I am not sure what. She is struggling to spit something, if there is any. And, now she has been spitting out mucus kind of a substance freauently. Kindly help me out immediately if someone has ever encountered such a thing. There are no proper facilities like vet on call or veterinary hospitals in my hometown. Attached photos of the same.
