Hi kalina, Thanks for your help! I appreciate it.
is it hard, soft, movable? Nope just her side seems to stick out and higher than the other. I have gently felt around and I do feel things just not sure...to me I think those are normal body parts I feel.
does it just seem like an extension of her body? yes
And she has no discomfort either....plays well...eats really well...but she is somewhat of a lazy and grumpy puppy meaning she don't play as often as my oldest one did and she is a bit grouchy with the other female, but not the male.

My male is always always ready to play. LOL!
After posting about the lump....I read on here where other pups got that lump after shot were given. So I think it is unreleated.
She does have a picky stomch that is for sure.
Thanks!!
