18 month old dog was castrated on Friday. He seems to be recovering well, eating and drinking fine etc. My only worry is the smell which I assume is coming from his wound. It has smelt bad like this since he came back from the vets. Is this normal? I know a smelly wound can be a sign of infection but as it has smelt like this since he first came back from surgery I don't think it is infected. I do have a very acute sense f smell though so could just be me. I have tried to clean the area gently a bit just now just in case it is just dried blood etc on his fur but he won't let me. we do have a post op check booked for tomorrow. I'm guessing I just want to know if this smell is normal? wound looks fine.
