Just buy the farm stuff, it's cheaper. Let me know exactly which one you get and I will tell you how much to put in a gallon or quart.

# Oxytetracycline

Package weighs 181.5 grams and has 10 grams oxytetracycline.

10 ÷ 181.5 = 0.055, which means it's 5.5% oxytetracycline, 94.5% filler

One gram  = 55mg

One teaspoon weighs about 3 grams which = 165mg x 5 teaspoons = 825 mg

The 800 mg dose for one gallon = 5 teaspoons (825mg is close enough)

# Oxytetracycline

This package weighs 280 grams

Package contains 102.4 grams oxytetracycline

102.4 /  280 = 0.37 , which means that it's 37% oxytetracycline and 63% filler

370 mg per gram

One teaspoon probably weighs 3 grams, so it's 3 x 370mg = 1110 mg per teaspoon

The 800 mg dose for one gallon = ~3/4 teaspoons

# Tetracycline Powder 5.5% (55mg per gram)

Package weighs 181 grams and has 10 grams tetracycline.

10 ÷ 181 = 0.055, which means it's 5.5% tetracycline, 94.5% filler

One gram  = 55mg

One tablespoon weighs about 10 grams which = 550 mg

800 ÷ 550 = 1.45 tablespoons

The 800 mg dose for one gallon = 1.5 tablespoons (825mg is close enough)

# Oxytetracycline - 343

102.4 /  135.5 = 0.76 , which means that it's 76% oxytetracycline and 24% filler

760 mg per gram

One teaspoon probably weighs 3 grams, so it's 3 x 760mg = 2280 mg per teaspoon

The 800 mg dose for one gallon = ~1/3 slightly rounded teaspoon

Im sorry, I dont mean to highjack this but as I was reading your post trying to figure out my dosage... my brain started to smoke haha I would apprecaite it if anyone can answer this question on dosage. I have been going through it with my poor lab and her heart worms.  I ran over to the tractor supply and got a power bag of Oxytetracycline but I cant for the life of me find the dosage for a dog and how to get it from power to water. If there is anything you can do, I would greatly appreciate it. I have been looking for HOURS! Its a 10 gram bag, 181.5 grams weight.  How in the world do I get 20 mg out of this bag? She weighs around 70lbs. Any help would be greatly appreciated!

Ok thank you for that. I have been reading conflicting dosage all over the place for dogs. Is that mixed in 1 gallon? And then how much of the gallon do I give her at once?

I think you need to give 4.25 teaspoons orally three times a day, which means you have to mix it in water and squirt it in her mouth.

Where did you see a recommendation of only 20 mg? And why are you wanting to give it?

That sounds like a lot to me, there is only 1 cup in the bag....so that wouldn't last hardly any time. I saw the 20 on the healthy pets site talking about dosage. On the package everything says in a gallon. She has heartworms, and im treating the infection side of it.
