My dog had umblical hernia surgery back in February 2024 I see a small leison next to the operated area which he constantly licks these days and same time he got netutered too. He licks the operated area as if he is in pain. The same behavior(whining and licking) we used to observe when he was in pain before getting operated. Could you please let me know what it is and why ? Anyway am going to consult his surgeon in two days as he is out station now.
