Diego I am so sorry to hear about your little angel ZsaZsa
. I know how you feel completely. I had to put my shelite, my best friend for 14 wonderful years down last July. It's been a year since, but the pain of missing him still remains even after I got my little Deegan. No one or nothing can ever replace the love that you and her had together.
One thing that helps me a bit is to know that I gave him the best life that he could of ever had. I spoiled him to bits, and loved him so much. And as long as you did that you know you did everything you could do and that she loved you just as much!
My deepest condolences to you and our family.
