A: Christina, thank-you for asking your question. To contain horses, you may want to consider horse fence, which has 2" x 4" openings. Please see model #348310B / Store SKU #197713.
A: Yes it should work
A: Hello, we do not recommend this application of the field fence.
A: 50 pounds?
A: This weighs about 70 pounds. Thank You, Jennifer Customer Care
A: It is very heavy
A: The roll weighs approximately 70 lbs.
A: If your dog broke through welded wire this fence will not be much different. We recommend setting up more of a heavy duty fence such as chain link. Thank You, Jennifer Customer Care
A: I put it up to contain llamas but it's short so it would need to be a small dog or one that doesn't jump. The bottom of the fence will need to be secure. Because of the field I put it in, I had to nail boards across the bottom of the fence line.
A: I think it would work for your dog seems strong and well made.
A: Yes, most dogs. Reference the spacing in the specs.
