There is one feature that stands out the most about the SportDOG® SDF-100A. It has the ability to contain more land than any other electric dog fence system, at 100 acres. This makes it a perfect choice for large rural properties. It also comes with double the amount of wire than any of the other dog fences do.

If your dog is large to very large, the SportDOG® fence is a great choice. Although the collar is rather big and bulky, this isn’t really a problem for larger dogs. A great thing about the SportDOG® collar is that it is completely waterproof. This is particularly important if you have water on your property. The collar is even submersible, so if your dog decides to go for a swim, you won’t have to worry about the collar getting ruined.

The batteries in the collar are not rechargeable. It depends on who you ask if they consider this a plus or a minus. The good news is that you don’t have to buy any special, expensive proprietary batteries. All that is needed are two 9-volt batteries, which are easy to obtain at your local discount store.

However, you should know that the batteries are a bit of a pain to change out. Because the collar is so strongly waterproofed, you will have to use a screwdriver to remove the 4 screws that hold the battery compartment on. But, the good news is that each battery change should last you around 6 months, depending on how many times the dog challenges the fence.

The system comes with a set of both long and short contact points. This is helpful because the longer contact points are needed if your dog’s fur is thick or long.

Compatibility is also a plus with the SportDOG® system. With this fence, you can pair most other PetSafe® dog fence collars. This is helpful if you also have a smaller dog that needs a lighter collar.

In conclusion, if you need a strong, durable system for your big dogs on a large rural property, you will make the right choice by going with the SportDOG SDF-100A dog fence.
