Hello & welcome, I am Dr. B, a licensed veterinarian & I would like to help you with your wee one today.
If she eating or drinking at all?
Any retching, gagging, lip licking, drooling, or vomiting?
Are her gums nice and pink (not white/pale)? Moist or sticky?
If you press on her belly, does she have any tensing, tenderness, discomfort, or pain?
How long have these lumps been appearing? Where are you seeing them on her specifically?
Can you take a photo of the lumps? If you can do so, this will let me see what you are seeing. To post them online, you can use the paperclip icon on the tool bar above your text box. Or if you can't see that on your computer/phone, then you can post them on any other site (ie Flickr,Photobucket, imgur, etc) and paste the web link here for me to check.
