My yellow lab just had a litter of 7 pups. They are 17 days old and 2 days ago one of the male pups developed a large growth on the top left side of his head. It is oval shaped, as big around as a .50 cent piece and it stretches from the base of his eyebrow to back of his head by his ear. It is as if we went to bed one night and it was not there and woke up the next day and it was there.
We have been watching it for 2 days and it has not grown nor has it shrunk. When we push on it, it feels squishy almost as if it filled with some kind of a fluid.
It does not seem to hurt him and he is eating, playing, and moving just like normal.
What is this? Please help!
