My dog is suddenly barking and snapping at other dogs that he used to play with... Any reason for this behaviour?

Dr. Tajunnisa M

Hi Aradhana. Is he drooling excessively? Is he sick? Any recent history of sickness?

Aradhana Sahoo

No drooling and no sickness.

Dr. Tajunnisa M

Is he neutered? Have you recently gave more attention to those dogs than him ? Is it happening while feeding or all the time ?
