I found a lump on Millie on her shoulder, above the R arm area...  I was concerned, but then I started feeling Ellie and she has a lump in the same place!!!  I will of course call the vet, but wanted your opinions... the dogs are 4 months old, so I thought that it was weird they are getting lumps already.  They did have rabies and their last distemper shots last week, but I thought they did the shot more in the neck area...

Thanks in advance for all of your help everyone!!

Thanks for all of the reassurance!  I think it is where the shots were, but I cannot remember for sure, and I would think they do the shot up more on the neck and the lump is more down on the shoulder, behind the arm.   They didn't get lumps from the distemer or bortadella.  Either way, I won't start worrying for a couple of weeks if they don't go away!
