Oh Connie! Hugs to you and Bosco! I went through this twice with my heart dog, Mia. The first time she was in the 50% survival group, relapsed 18 months later and sadly, passed away from complications. There is absolutely nothing you could have done to prevent this. IMHA strikes randomly.
Dawn has given you some excellent info. I tell people that fighting this disease is like riding a roller coaster blindfolded. You have no idea whether or not you're going up or down, have no idea which way you are going to turn and every twist leaves you breathless. Know that it can take months to reach remission and that recovery is one step forward, two steps back. The first time Mia got sick, she did not reach full remission until 17 months had passed. I am lucky enough to live near a specialty hospital and they were very aggressive in her treatment. She has 2 transfusions, a 4 day hospital stay, several months of blood tests every other week and it was nearly a year before she was in a normal range and remained there. Once a dog has had IMHA, their immune systems are considered "sensitized" for IMHA. You want to avoid stimulating it.When Bosco reaches remission (thinking positively!!) you want to avoid Clavamox, keep other oral antibiotics to a minimum, avoid unecessary vaccinations and anything else that could stimulate his immune systerm.
There are organizations that financially help those whose dogs have life threatening medical issues. I have included a link to info provided by a local organization called FACE.http://www.face4pets.org/Files/RESOURCE ... 20NEED.pdf
Hopefully, you can access help from one of these providers.
Good luck and please keep us posted on Bosco's progress!
