Sorry for the delayed response.  It's been a week!!  This is a long reply.  I will start from the beginning.  We adopted Bronx on July 21st and by July 22nd I was messaging the rescue concerned about how fast he was breathing and that he was in pain.  When we rescued him they told us they had had his leg vet checked and that he had only carpal flexural deformity,(this was a lie as we found out no xray had been done like they said) and that there was no pain with it and all was good.  I was still concerned about his breathing so took him to the emergency vet who said they thought the breathing was due to pain, and started him on an anti inflammatory pain killer.  I again contacted the rescue to let them know.  I then called my vet and got an appointment set up for another opinion on his leg.  Sadly we never made that appointment as on July 27 he tripped over his bad leg while walking!! and broke it.  Back to the emergency we went.  Upon arrival and before any xrays the vet immediately knew more was wrong, as he shouldn't have broke his leg that easily. Xrays confirmed a break but also severe elbow dysplasia, arthritis, carpal flexural deformity as well as u shaped brittle bones in that leg, as well as old poorly healed breaks.   He was clearly very abused and neglected.  He had also lost all muscle mass in his leg and shoulder from not using the leg.  She recommended amputation (she said even without the break she would recommend amputation. She also didnt think pinning the break would work, given how thin and brittle his bones were and the shape the rest of the leg was in) she sent a consult off to be sure it was the right decision and that his remaining legs were healthy and could support him.   The surgery went great!! and the incision is looking great now.  We did however end up back at the vet last night as his breathing was still very concerning.  I was worried he may need better pain meds.  Turns out he doesn't have much pain as there was zero reaction to the vet pushing on the incision.  She did a cbc, heartworm snap test, temperature and listened to his heart and lungs.  All that checked out great, but....his chest xray shows lung patterns that she thinks may be blasto.  We are doing the blasto test on Friday.  My new question is now is it okay to wait until Friday to test for blasto if his breathing is already fast?  We also found out last night that the rescue knew his breathing was too fast before we brought him home but did nothing.  Our vet and I are currently talking with the rescue about how they need to pay for all these issues as they were known and lied about, (they don't seem to care) especiallysince the issues were very obvious from day one.  My vet is amazing and we have agreed that he will get all necessary treatments he needs and we will figure the financials somehow after.  He is the sweetest dog ever.  He loves everyone and everything he meets.  At only 10 months old he has had a very unfair start to life and definitely deserves so much better.  He was failed by so many people already, hopefully this is the start of healing and a better life for him.  He is amazing given everything he has been through.  He is so calm and docile, he is definitely a gentle giant.
