Glucosamine would be given to a dog to treat Arthritis, pains from natural aging, or to treat hip dysplasia. It has been proven to be very effective in treating the above.
Well I'm not a vet, but I am a vet tech. I know the doctors at the clinic I work at recomend to give human glucosamine supplenments to patients all the time (that usually have joint issues). You could also find a good dog food that have Glucosamine in it. Glucosamine is glucosamine. It is a supplement and is not dog/human specigic. Glucosamine with Chondroitin works well too.
The standard amount of glucosamine and chondroitin that should be given to your dog is 20mg's per pound of weight, so in the case of your 20lb dog the amount of glucosamine and chondroitin would be 500mg's. You should try getting a supplement that also contains a natural anti-inflammatory such as MSM alongside glucosamine and chondroitin to help ease the pain and swelling that so often occurs with joint pain in dogs.
Considering that glucosomine does not work anyway why not?
This would be a good question for your veterinarian, as the answer will depend upon your dog's health status. However, there is very little evidence that glucosamine does anything for your dog's joint health.
If Niall from One Direction was to give the gift of a dog to someone, He would get one from a shelter. He would also give the person the type of dog they might want.
Amazing dogs can take a lot of the same medications and supplements that humans can, not all but some. For stiff joints both people and animals need glucosamine. Glucosamine is also given to older horses to help with stiff joints. Talk to your veterinarian about specific dosages for your dog.
I would suggest none - there is no evidence that glucosamine has any positive effects for your dog's health and it may interfere with other medications he may be taking. It tends to be expensive, and in the United States at least there is no control over the concentration, potency or efficacy of nutritional supplements.
Maybe they don't have enough money to give the dog shots or feed it food. Maybe they really want to keep it but it just isn't working out. There are many reasons for people to give up their dog, as sad as it may seem.
It depends on the weight of the dog. I'd suggest that you check with a vet. Prednisone, when not used correctly can harm the dog. It is a great drug, but it can also be a dangerous one without professional guidance.
It matters how much, they may become a little sick or very sick
Why would you even want to give that to your dog? Do NOT give it to your dog. If you think your dog is ill or possibly has diabetes, take your dog to your Veterinarian for a check up.
Give them to someone with a dog.
