I am an animal lover, and dogs are my animal that I just adore. I have 2 of my own. Honestly, if I could afford it, was in better health myself, and my kids were grown I would have many more dogs. They love us unconditionally and are always happy to see us. I know that they require lots of attention, and more physically than I can give with my physical limitations now, so I will not get anymore. I really shouldn't have the 2 I DO have, but we have had them forever, and I will not get rid of them because they are family. We do the best we can and I get them as much excersize as I can manage to, and all of my kids and hubby help with that as often as they can too.
All of that being said, I also believe that the people in your family have to come before the dogs. I have had medical things come up personally that we couldn't afford, and I had to put them off for ME. (a human not a dog) You need to ask yourself a few hard questions about your dog and your situation. First, is your dog in pain all the time? Is the pain something that can be controlled with a less expensive medication since you said yourself that the dog is managing to get around quite well. Second, what are the actual costs of the dogs procedure and follow ups going to be. There will be additional costs other than surgery and xrays, like meds, follow up appts, and sometimes even an overnight stay at the vet. You need to know EVERY COST, so you can make a very informed choice. Third, what would it do to your family's finances if you chose to go ahead with the medical procedures for the dog? WOuld it cost so much that you would deplete your savings, or would this actually mean that other bills wouldn't get paid on time, that you wouold need to "juggle" bills to keep utilities going, and buying needed items for your family would be a hardship after? This is very important, because one of your jobs as a parent is to make sure that you can provide for your family and protect your family. What would happen if your child or even you got sick after the dog had the procedure done? Would you have the money to take care of yourself or your child properly? Could you buy any and all medications that may be needed? I know that you may have medical insurance, but they don't cover everything.
If you are lucky and SMART enough at this point to have some savings set aside, will using that possibly jeaporidize your security in the near future at all? What if your husband/ child's father were to get sick and be out of work for even a week? How would that effect you financially. I am not talking about really horrible illness, but even just the flu. It is coming into the flu season, and I know a lot of families who would be devastated by even a week or 2 without their normal income. If you currently have money set aside and could use that in a situation such as that, I would be inclined to say leave it there so you have that security. THese are the things that you need to ask yourself BEFORE making a choice, (probably quite an emotional one at that) about your beloved dog.
Also, I would look into the costs, and the what if's if you didn't have the procedures done. (I would want to know if there was any way the dog could live COMFORTABLY without doing the surgery. ) Maybe an alternate treatment? Then I would call around to other vets, and look for other opinions. You don't need to even go in and incur a charge, just explain over the phone what they (your vet) told you was needed and the cost. ASk if they did that procedure and for how much? I would look into vets in the community who do volunteer work at vet clinics. (We have one called Pet Luv) They usually only do shots and spay/ neuter, but in this situation you may find a vet who would be willing to help you out. Call the shelters and rescues to see if any of them have or know of any type of fund to help out. Explain to them that you don't want your dog to have to suffer, but you simply cannot afford the treatment. You may find that there is some type of help available, even if it's the vet they use who is willing to do the procedure for half the cost or less.
This is very hard. You love your dog, but NONE of us expect that we will be faced with vet bills totalling in the thousands when we get a dog. (at the most hundreds, but thousands, no) It does NOT make you an irresponsible pet owner. IF you have no option than to have your dog put down to keep him from being in pain, well then as difficult as that will be, it is the least selfish thing you could do. AT least you are not just saying hey, he is fine with 3 legs........ we don't need to do anything! You love your dog, but you love your family too, and you need to be able to take care of them as well. If you are paying off a huge vet bill, will you be able to afford to take care of your child or children? Well, I am so sorry that you are going through this. I know how much it stinks! I wish you the best outcome. Maybe you will find a vet who will work with you on the cost and take monthly payments. Good luck! I know how hard this is! You are a great dog owner, and you didn't do anything wrong! Best to you!!
