Inflammation or something else?
My dog has a strange wound on his teat (see picture)
It is very warm around her teat, she is also behaving a bit strangely, I think it is pain
we have a vet appointment tonight
Nevertheless, I would like to know if you have any experience or if you know what it could be
thanks in advance
According to the picture it looks like the teat is injured so it's good that you have an appointment as the vet is responsible
If she has puppies, there could have been teeth there, or something like a bush, thorns, or wire. It could be harmless, but since your dog is also behaving strangely, it could also be an infection.
These are places where they can be really harmless or very serious, so there must always be a vet
Your vet has the answer. Just wait, the appointment is today.
