A street puppy (about 8 months old) died in my vicinity. Cause of death was unknown, but following symptoms were visible in his body:
- He developed a dewlap (major symptom).
- It seemed that he had congestion in his throat, he coughed a lot.
- He refused to consume 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 visible 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?
