Lilly is a German Shepperd about 4 years old. On Feb 23rd she was spayed, and the operation went well. A few days after coming home, one of her tits (right next to the spay wound) started to grow. A couple of days later it was full of milk.
The wound of the operation healed nice. I figured she might be running a false pregnancy, but only this one tit got big, the rest are normal. She constantly licks it so I thought she might be stimulating it herself, so I have been giving it time.
It is now a month later, and the situation continues. It has reduced in size, but is big enough that at the park other people asked me if she just had babies. She doesn't seem to be in pain, eats well and is otherwise perfectly healthy.
I haven't taken her to the vet, I expected it to go down with time. It has come down some, and she is barely producing milk now. Again, I think as she stops licking them the stimulation stops and they reduce in size.
I took her to the park the other day and a friend of mine was there with her male dog. He spent the whole time after her, almost like she was in heat. But it has been a good 8 weeks since the spay, so I am not sure if she is putting out some hormones she shouldn't or maybe he is just a horny dog... :-/
