I went through CHF with my last cocker. He was on a lot of the same meds yours in on. Every once in a while, I would take him in and his doctor would give him a shot for the extra fluid in his lungs. Be prepared to stop for potty break on way home. Bailey starting to pull away from us, went off by himself. To me, he was preparing us for his departure. He finally starting getting seizures and his doctor said it was from lack of oxygen reaching his brain. He could no longer walk and I would carry him outside for potty and to see his friends. My husband was totally against making the decision but one day we had no choice. My guilt comes from waiting too long. But, I had hubby to contend with. I just hope my Bailey Boy knew I was there at the end holding him. God Bless you and your baby. It is hard.
