My puppy has a lump under skin near shoulder. Should I see a vet?

Pet's info: Dog | Mixed Breed | Male | neutered | 2 months and 8 days old | 17 lbs

My 9 week old corgipoo has some sort of weird lump under his skin. It’s around his shoulder blade, under the skin (there are no signs of visible irritation- like redness), it feels to be a bit of an irregular shape (maybe 1/4 inch long), and one part of it is more firm that the other part. I put pressure on it and he doesn’t seem to care. Any idea what this could be? He has a vet appointment for his next set of shots Dec 28, should I wait or get him an extra appointment before that?

This is a common location for a vaccine to be given. Has he recently had puppy vaccines? If so, this is likely just a local reaction and no big deal. You can keep watching it. If he hasn’t had shots recently or if you don’t think a vaccine was given there or if it is growing, I would have your vet take a look at it before his next set of shots. Your vet will be able to do a cytology if needed and determine the type of mass it is. I hope this helps!
