This is me freaking out...

 Gulp, I do know this feeling!  For me, this normally happens on Saturday, about an hour after my regular vet has closed -- and with a Monday holiday.

The first one, on Maze, since it is not 'attached,' I've been told that is a good thing and not to worry.  The other one, I think I'd have a vet check it out sooner rather than later.

Please give them both some cuddles from me!

 I'd take her in now but I'm still 2 months away from working... gonna save what I can and see what I can do..

 Just seeing this - Maze's is likely a lipoma or benign fatty lump. B has developed a couple of those

FWIW my vet aspirates the lumps and it doesn't cost much to do that - if it goes to the lab then its more expensive but still not killer

They can tell right there if its just a fatty tumor or not and usually can tell whether its a cyst (Sandy's might be a cyst)

Hoping all is OK - I have learned that lumps are part of them getting older :(

I just went through this with Nikon.  I found two lumps.  He's had sebaceous cysts before and they've always popped and then dissolved on their own, but one of his lumps got really "angry"....hard, red, irritated looking.  Of course I freaked myself out thinking he's only four and has mast cell tumors.  I took him to my vet and my vet said they are benign cysts.  We are planning to remove the one on his leg only because Nikon has been chewing on it and is now irritating and damaging other tissue on his leg.

At my vet, they don't charge anything for the fine needle aspiration, it's just part of a routine exam. If lab work is needed that would cost more, but usually they can tell you right away under a microscope if it's a lipoma, sebaceous cyst, MCT, etc.

  I agree that Maze's is probably a lipoma; Jessie is 14 and has several of them. My vet does a needle aspirate and I know within about 15 minutes if it's anything serious. About Sandy's lump; is it attached directly to her rib cage (bone)? Jessie has a large lipoma close to her rib cage. It feels hard and does not move because it's under some muscle. Hopefully, that's the case with Sandy. Most lumps found on dogs are not serious. (((hugs)))

 Well Sandy's lump hasn't changed at all in size and it doesn't seem to bug her (as long as no one touches it. ) I spoke to my vet and they said to keep an eye on it and if it changes in size, bring her in.

Maze's lump hadn't changed either.. It's just a lump on her chest. LOL. 

 If you look at the lumps daily, you may not notice a change if they're growing slowly. My vet said to trace them using waxed paper, and use that to check them every few weeks.

Absolutely what Janice said --

I don't let ANY lumps just "go".  PARTICULARLY not something that is "attached".  Like Janice's vet -- mine wil aspirate (meaning they take a syringe and withdraw some of the fluid -- or whatever -- from inside the lump and they go look at that stuff under the microscope.  If it's fat then it's likely a lipoma .. but if it's not they KNOW.  Or maybe, like Janice said, the vet says "Hmmm, I want the lab to look at this" --

 For the vet to aspirate it and look at it themselves shouldn't be expensive.  I've had some "lumps" just stay for a long time, but if it changes in ANY way then the vet will want to remove it.  But I wouldn't totally wait beforey you have the vet see it.  Some things may grow UNDER the skin and you don't know it's getting larger. 

 Callie, as soon as I'm able, I am taking Sandy into the vet to have it checked. Her's is worrying me the most just because of where it is and how solid it it..  I check it every few days thou I think I will trace it (she'll be soo impressed. Lol)
