Ok everyone, quick update...
My wife just heard from the vet, surgery went very very well. Although the mass appeared to be over the knee joint, it was actually lower than what everyone thought-this means.... No skin flap!!
She was able to get the wound closed without too much pulling on the sutures and feels confident that she has a good, strong closure and range of motion tests looked great!

I couldn't wait to share the news, but will be posting more in a few hours after we collect our puppers.

Alright everypawdy, we are home! Well, our temporary home at least.
Zuzu's surgery went very well, better than expected. The tumor was lower than the knee joint so we were able to get good closure without the need for a skin flap!
Doc says she got good margins (I of course forgot to ask how wide as I was so excited when we picked her up-will make sure to ask)

Surgery lasted about an hour and a half, she did great with anesthesia. They gave her hydromorphone injection and a nerve block as well as IV rimydal. They said they used the laser after as well, since they see great improvement in healing with it.

After surgery she was giving everyone a laugh. She would suddenly and randomly howl for a few seconds, then stop and look at everyone like " what? That wasn't me". The first time she did it it scared the doc so bad she almost fell out of her chair! Then she would be quiet just long enough for people to forget or someone new to walk in the back and the whole thing would start again- so adorable!

So the door to the back of the clinic has a window in it, so we were able to see Zuzu as she was being brought up to us. She was hobbling along, not putting much weight on her back leg but WAS walking. They came through the door and she saw us and then she acted like she couldn't walk! She did trip on the slick floor and have a fall- poor baby. When she fell her wound started seeping. It looked like straight up blood so the tech went and got the doc to look at it, she came out and said it was ok, that it was gonna do that and not to be too worried about it unless it started showing signs of infection.
We then had the techs help us get her in the car. We get home and guess what- she won't walk, won't even stand and is just letting her legs collapse. I wasn't too worried cuz I just saw her walking and even the techs that helped us were giving her a hard time about pretending not to be mobile in front of us.

So, because they didn't do the belly flap we were able to use the get a grip harness supplied to us by tripawds. We got it on and lifted her out of the back of the car- still wouldn't put her damn feet down so we ended up awkwardly carrying her through the parking lot and down the steps and into the apartment.

After about a half hour inside we decided to take the cone off,I know I know it's there for a reason, however we are within arm's reach of her and she has at minimum two sets of eyes on her constantly. She was finally calming down and resting after the cone removal.

She's been pretty calm, a little bit of whining, but not too bad. She wasn't much interested in drinking, so we put some beef broth in her water, and that send to help some. She's also had a bit to eat. We tried going outside once, but wasn't interested in doing anything. She did pee for the techs before we picked her up, so as long as she goes in the morning I think we're good.

It's now 230am and zuzu is wide awake and whining like crazy. I thought it was because I put the cone on so I could go to sleep, so I took it off to see if the whining would stop. It did for a while, now she's back to it. This is also about the time her hospital meds are wearing off. She's not panting, not breathing heavy, but did get up and move around a little. Not sure if that's her showing pain or if it's more of a " trying to get comfortable" sort of deal. She does stop whining as soon as I pet her and gets a smile on her face. It should be noted that zuzu likes to whine for attention and to get her way. If this continues the rest of the night, we'll be calling the vet first thing in the morning.

Zuzu is much much better today. She even pooped for us about an hour ago. Yay poo!

I am extremely confident that her whining was more attention seeking than pain. As soon as my wife woke up and started giving Zuzu attention her whining basically stopped. So I guess last night was one of those times that I just wasn't good enough and she wanted #1 Mommy.

The cone will be used tonight, whether she likes it or not. We can't afford an infection and even though she gets super anxious, she's gonna have to deal with it. We will look into medical intervention if the anxiety produces results similar to last night, but I'm crossing my fingers that tonight goes a bit smoother.

Initially Zuzu didn't want to use her leg, but is putting more and more weight on it as the day has progressed. I was starting to get a little nervous that she didn't want to use it. I think part of the problem is getting stiff with so much lying around. She has also started beefing the knee a bit more, compared to just leaving it straight.

I have pictures, but have to wait until I'm on the computer- posting pictures from my phone is just a bit too difficult.

Thanks so much! Last night was a huge improvement, even with the cone on, we (mostly) slept through the night! She was up a few times to adjust but overall did so, so much better, and her"preferred" momma wasn't even here!

I'm so glad we were able to get to Zuzu's before there was any Bone involvement. I know amputation is the curative option, but I'm really happy we're able to go this route first, I think it's a good option for zuzu and our situation. Hopefully biopsy results aren't too bad and we can count this sucker out for a while. No matter what our days will be filled with yummy treats, long walks (once approved), lots of scratches and cuddles and infinite praises.
