We have run 100 cow/calf operation for 30 years and use the Stockdoctor when cows are out on pasture. We also ran 600 yearlings on pasture for 5 years. The Stockdoctor is a very useful tool to use out on the range for cattle with hoof rot or pneumonia. Cattle can be a long distance from the handling system and when they are sick its too far and too stressful to move the animal. In such situations we rely on the Stockdoctor. We actually have 2 stockdoctor tools. We can preload the right dose, and have it divided to be delivered in two sites. As you know cows can get cranky and usually run off after treated. We’ve had good success with two people approaching and using the 2 Stockdoctor tools. The Stockdoctor is very light weight, easy to carry and handle. You need to get a good straight on hit and the needle will stay in the animal to deliver the dose. The cuff pulls the needle out as the animal moves away. The only problem I encountered was the syringe flying out of the cuff and would sometimes be hard to find in the grass so I have tied a streamer of flagging tape to the syringe barrel which does not interfere with the function of the tool. The syringe all unscrews for easy cleaning. I like that there is a lot of thread on the screws so the needle is very secure. The plunger can at first be a little tricky to engage, but be calm and follow the instructions in the instruction book. We have even used the Stockdoctor on animals in the corral that are too ornery to move into the handling system. For twenty years the Stockdoctor has been a stress reducer for treating animals. Treatment results have also been successful, and I will continue to use the Stockdoctor tool. Also replacement parts are available at, they have a very detailed website and response time is great.

The Stockdoctor II has allowed me to treat my individual cattle and my calves with great convenience and ease where it is the most difficult, in the open range setting. And it is so reliable I am not afraid to use my more expensive treatments like Draxxin where I was with the other more unreliable remote delivery methods like darts. Even on my cattle in the more confined setting, its considerably easier than the hassle of sorting an individual animal out.

Like the Stockdoctor because of its accuracy when injecting an animal, the slow release of the medication and the revival of syringe. Can also inject larger amounts if I need to. Have used the same Stockdoctor for about the past 10 years, still works great!

The Stockdoctor is very good for out on the farm. I have used it for a long time maybe since the early 90s. I keep it in my feed truck all the time, just recently bought a dart gun and you are limited on medicine. At least on the Stockdoctor you can add 30cc. I just ordered 2 needles. And by the way thanks. It has got me out of a bind on several occasions.

We have used the Stockdoctor for many years. We have been able to deliver medicine to our animals without the stress of moving the herd to a facility as well as the issues of wrangling up help. The Stockdoctor works great for our cow/calf operation.

StockDoctor II™ Medicating System Review by Chad Olson

Chad Olson, North Dakota, USA

When I first started raising cattle, treating them in the pasture during the summer months was often stressful not only to the cow being treated but for the entire herd. Setting up a holding pen and chasing the cattle around the pasture just to catch one or two was, for me, not the best plan. I began searching for a better method and was introduced to the Stock Doctor about 4 years ago. Since then, I can treat a cow in a fraction of the time it takes using the old method. VanderBuilt Systems™ has truly developed a great product.

I would highly recommend this product. Purchased in 1995, still use it today. Not having to bring in the whole herd to treat one cow saves time, with less stress on the cattle. The employees are super to work with, very helpful.

We have used the stock doctor in the summer months for many years. We have several pastures with no way to catch the cows/calves to doctor them for bad eyes. The stock doctor works great for our cow/calf operation.

Thanks, Tracy Hill

StockDoctor II™ Medicating System Review by Jason Gradeless

The StockDoctor has become a useful tool on my farm. It saves large amounts of time and labor; instead of bringing in cattle to the chute I can treat them in the field. I use it off an ATV and believe it has helped with over all herd health being able to treat things like pink eye immediately. The unit is extremely tough, I’ve used it for 7 years and had zero trouble.

StockDoctor II™ Medicating System Review by Christoph Weißenbach

Christoph Weißenbach, Austria

I am an Austrian farm boy and we are using the Stockdoctor on our alpine pasture to medicate the beef cows and their calves. It is a very easy way to medicate cattle without constraining or catching the animal and you can do it without disturbing your herd. So for the Austrian alpine pastures, it’s a very nice and price worth system to medicate free running herds.
