pea sized lump on neck

[Sophie48]

hi - our 15 month old frenchie sophie has lumps under her neck about where her collar line is - on one side there is a pea sized lump and on the other several smaller bumps or lumps - along with some hair loss. anybody have any idea what might be causing this? could it be her collar? food allergies? why is it only where her collar seems to be?

thanks for any advice.

It could be lots of things. It's probably a good idea to go to the vet. If its itching your pup and its missing hair it could be mites. But its probably best to go to the vet. Best of luck.
