SouthernGirl, i knew from previous posts that you are on budget and i can understand about not having money. I know you and your mom are helping out multiple dogs there, too. Almost all the vets i know did not go into the field as an attempt to get rich, but to help animals...........and most vets i know are generally kind loving ppl, imo.
You've obviously never met a large animal (horse) vet. There all a bunch of grumpy old men that I swear are there to intimidate you and make you feel stupid and inferior.
On the other side, I agree, most small animal vets (for like dog + cats) have a real passion for the animals they're dealing with and are very helpful and will usually quite happily give you information over the phone or in the clinic about how to help with elderly dogs and joint pain free of charge.
Also remember when looking into herbal remedies that a lot of herbal remedies available in Holland (please don't take offence to this) are often illegal in other countries. Just because you CAN buy it online, does NOT mean it's legal to have it sent to your country.
Glucosamine is great for any animal with joint problems such as arthritis or degenertaive bone disease; it's always recoomended for dogs, horses and humans. Other things such as MSM may help, but I'd be calling your vet and asking their opinion (over the phone if necessary - as I said they're nearly always happy to give you some free information and might even be able to prescribe you some medications without having to take your boy to the vet).
Good luck! It's not a nice thing to go through - you just have to (as said above) take lots of pictures and think of all the good times you had together - and obviously keep his pain as low as possible.
This thread made me sad as the dog I grew up with is also at this age (~14-15), is mostly blind, deaf, but as she's a small dog she doesnt yet have any joint problems and still bounces around happily, but she's skinny (she was NEVER a solid dog to begin with) and it makes me sad because my parents also wont take her to the vet due to the cost.
Good luck
