Vitamin C for Pets

Last Modified on Feb 19, 2015

There are a number of things that you can do at home for your pet to slow down the progression of arthritis and help your dog to stay healthy and as pain free as possible.

The first solution is to incorporate substantial doses of powdered Vitamin C into the dog's daily meal. Vitamin C will help keep tissue healthy and protect against further joint deterioration. (Use a sodium ascorbate or another form of buffered vitamin C, as plain ascorbic acid may cause an upset stomach.)

Here is a daily dosage guide for adult dogs:
Small dogs: 500mg - 1,000mg
Medium - Large dogs: 1,000mg - 2,000mg
Giant dogs: 2,000mg - 4,000mg

Start with the lowest recommended dosage and gradually increase it once or twice per year. If the dog is producing loose stools the dosage may be a bit high so cut back slightly and increase it gradually over time.

[YEA]  My cat was lethargic, drinking extra water, and his coat lacked shine. I had great luck using powdered ascorbic acid (vitamin C) mixed with water for this condition. I put a half teaspoon into a small cup, added water, then used a plastic syringe (available at drugstores) to give to my cat orally.

The next morning after giving vitamin C, he was plumper, healthier, and happy. I will continue to give him 250 mg a day for now to take care of any problems he mght be experiencing with his kidneys. Apparently the max dose is 250 a day for cats.

I was getting worried about my kitty and am so happy to see him improving so rapidly! High dose vitamin C therapy prevents all kinds of human diseases as well!

Thank you so much on your message of giving your cat Vit.C " I was actually searching for my dogs ailments, but then I noticed where you wrote your cat drinking a lot of water as I have two cats doing this. I need to look for the Vit. C. Thank you for sharing very important and helpful information.

I started giving my 7 1/2 year old Weimaraner Ester-C and it is working amazingly well. The before Ester-C symptoms were holding up her rear leg and refusing to put pressure on it, and sleeping all the time (perhaps depressed). She is normally a very, very active dog. Three days after treatment she is running around, energetic and putting more weight on it. Two weeks after the treatment she is as energetic as she was when she was a puppy, putting weight on her leg and 80% symptom free. This is truly amazing progress!! I started 1000mg of the Ester-C and up to 2000mg after the fourth day. THANK GOODNESS for natural cures and the internet!!

[YEA]  I've not read many posts. I wonder if folk realise that dogs & cats don't make as much vitamin C as most other animals do?

I gave a home to a stray cat who possibly had a poor start in life. When he became very poorly, I gave him 1/4 tsp powdered sodium ascorbate dissolved in 2ml warm water, used an old syringe [no needle]to inject it into his mouth. I did this at least 2 hourly during waking hours. The effect was wonderful!

He has a tendency to get discharging eyes. I use 1tsp sodium ascorbate in 1/2 metric cup warm water & swab both eyes 3-4 times/day with great clear up. [I drink the left-over solution.]

A friend who breeds rottweilers has a prize dog that's asthmatic. The asthma cleared up with ascorbic acid several times/day. The dog came off all its meds.

[YEA]  When my male cocker spaniel was about 6 months old, symptoms of hip dysplasia showed up dramatically. In a very short time he was almost crippled. After praying (God is good!), I began giving him 2,000 mg. of buffered C daily. Within a few days, he was walking & running like a normal pup. When I discontinued the C, the symptoms reoccurred, so I kept him on it continually. He is 12 years old now, is quite healthy, and still walks/runs without a problem. He has an unusually healthy diet, including apple cider vinegar & other supplements, and he and his twin sister are incredibly young for their age!

[YEA]   Vitamin C is great for dogs. I have used it with my Greater Swiss Mountain Dogs for years. The one thing that is really important that I didn't see above is the you can NOT give dogs normal vitamin C which is ascorbic acid. It is very easy to burn there stomachs with ascorbic acid. Calcium Ascorbate or Sodium Ascorbate are what you need. Ester C is great too.

I am desperately trying to find a good quality Vit C powder to give my animals. Value Plus in Aus used to supply it, but doesn't anymore. Can anyone help me please. Thanks, Carol

[YEA]   Carol; I use the powdered Ester C for my cats and dogs. The only thing it says on it is Ester C natural flavor/24 hour immune support, also explains all the positive results etc. Good Luck

[YEA]   The vitamin C I used is a whole food type by Healthforce Nutritionals. It's a complete form of VC, not an isolate like ascorbic acid is so the body can make use of it without having to rob the body of rutin, bioflavonoids and such, to remake a complete, useable molecule.

My 2 yr old, 80 lb Dogo Argentino gets 325 mg 3 times a day to combat arthritis and chronic ear infections.

[YEA]   As an afterthought ~ vitamin C works in conjunction with other nutrients for it's activation. If you aren't doing a raw diet, where they get their calcium and magnesium (along with so many other nutrients) from eating raw bones, you should supplement. If you are using ascorbic acid or some other isolate form of vitamin c you should also supplement bioflavonoids. Lastly, Steroids medication deplete vitamin C, so you'll need higher dosage till you wean off the drugs and heat destroys VC so don't do that :o)
