A street puppy (about 8 months old) died in my vicinity. Reason of death was unknown but following symptoms were visible in his body:
- He developed a dewlap (major symptom).
- It seemed that he have congestion in his throat, he coughed a lot.
- He refused to eat anything, water too. He became quiet.
It seemed that he wanted to eat, he would come and sniff the eatable, but didn't eat.
There were no other visibility symptoms in his body. He was healthy. It was winter and in 4 days he died. His body was a little swollen after he died.
What could be the reason for the dewlap he developed and his death?
