Also talk to your vet about possible tranquilizers during the time you need to keep him from playing rough, etc. I don't know how you feel about medications, but sometimes, it just makes things easier on you and your dog. One of my dogs, a rescue, cut one of his foot pads this past summer. He is VERY high energy and the vet told me I had to keep him quiet for at least four weeks. WHAT? How on earth am I suppose to do that? So, I asked about tranqs and she agreed. They were dirt cheap and I didn't knock him out, just enough to make him sleepy. I also had to make sure the bandage didn't get wet and it was doing nothing but raining...what a nightmare. They devised a boot for his foot, out of an IV bag...quite amazing and it helped, but I spent a fortune on bandages because as soon as it got wet, I had to change the dressing. Spent a ton of time doing that. In any case, as Sherrine said, I'm a firm believer in giving back to our buddies. I realize you are in a very difficult financial situation and it isn't easy, but we do what we need to do for our loved ones. And I would think your vet would work out a payment plan with you.
We had a Golden, named Shannon, my beautiful, beautiful girl that was diagnosed with lymphoma at the young age of 6. My husband was unemployed at the time. The vet told me that if we did nothing, she'd be dead in a month. If we did chemo, we could add three years to her life (up to 3 years). We ended up taking her to a specialist, yep, veterinary oncologist, and she received chemo for 15 months. She went into remission three times and honestly, the chemo did not seem to affect her like it does humans. She really had a wonderful quality of life during that time. Cost? Over $10,000 and as I said, my husband was out of work but neither of us could imagine not doing it.
Sorry for the ramble, but you get me started on dogs and well...there I go....
I really hope Mr. Murphy gets better very, very soon!
