Thanks everyone for you kind words and advice.  Just when i think i have made up my mind, i change it again.  Im running out of time to change my mind.  I have booked poppet in for xrays tomorrow, being the chest and legs/pelvis.  Want to see what is going on in there before i make the final decision.  If the lungs are clear and the leg is still deteriorating i will advise them to keep going and do the amputation as i know she is in some pain.  At this point im not going to put her through a more invasive biopsy to get a result.  They can biopsy the leg afterwards.    They are saying tho, without the biopsy before hand that they cannot advise if the cancer is osteo or myeloma, and if it is the myeloma then they may be able to throw different chemo at it (than the one she is on) and there may be a 50% chance she would use the leg again to some degree (and be made comfortable) with some medication i presume.  Obviously money comes into the equation (i wish it didnt, but having a family it does) and im trying to do the right thing by all.  If the xrays are bad, i will go for pallative care for a little while.  Being human, im still finding it hard to take off the leg.  Is she going to look at me and wonder why i did this to her ?   Silly i know, but i know that she looks up to me for assurance.  Thanks again everyone. Kaz & Poppet.

Well, poppet had her xrays this morning and all are ok.  Clear chest and all over except the "leg".  Have decided to remove leg as she has lost her spark and i believe its the pain and meds which are causing this as she still wants to run with me whenever i go outside.  So this afternoon Poppet will join the Tripawds ranks (all going well).  Thank you all very much for your words and for being a sounding board for me.  I think the best bit of advice i have gotten here (and even my partner now keeps repeating it to me) is that im not removing the leg, im removing the pain and giving her another chance (no matter how small) of enjoying life to its fullest.

Thanks again Kaz & Poppet....

Hi Everyone,  Poppy the "tripawd" is doing really well.  The vets were amazed.  She is getting around just fine.  A few bumps into things, but otherwise going really well.  I let her walk for about 100m and then back for a rest.  She wants to take off into the paddocks.  She is giving the wound an occasional lick, but we have some bitters to put around it and she doesnt like the taste of that.  The bruising has gone down today and it doesnt look as angry.  what i have noticed tho is that her other leg seem to be a little swollen and under the hair, very red, like this leg has been bruised too.  Not sure about this.  I hope we have not been doing too much moving around, or could it be that she is lying on that side all the time ?  She has a little bit of swelling (odema) behind her front leg, on her chest, presume from lying down on that side all the time too.  I did start to have that thought today of "i have done the wrong thing here" what kind of life is this just sitting around with the occasional walk, watching the world go by, but, that is what she was doing before the operation anyway and probably has been that way for the last year.  So maybe i need to calm down and just see how we go.  Its not my week, cause my 15yr old dog buddy fell over last nite, and with a suspected fracture, he was stressed out and due to arthritis could not take any weight on his other legs.  I called the vet at midnite (who happened to be the same vet who operated on poppy) he came around & could not find a fracture, gave buddy some pain killer and said to review in 24 hrs.  12 hrs later with buddy still not taking weight on legs i resigned myself to the fact that he would have to go to doggy heaven (even rang my son who was at his dads to tell him).  On seeing the vet, Buddy decided that he was not going anywhere today and proceeded to hobble around for us.  Vet reviewed, said he may improve once the pain killers wear off further and see how he goes over the next few days.  I now have the "2" geriatrics holled up together (im sure it was a plot) in our garage, on beds and blankets, being waited on and spoilt.  What a stunt to pull just to get back with your girlfriend.  I swear, im emotionally worn out.  The vet said i had spent that much with them over the past week, so my last consultation was "no charge"...  Off to check the terrible twosome and then off to bed for some well deserved rest.  Thanks everyone.  Kaz & Poppet.
