What is the best size for a Havanese?
jossr on Jul 24, 2014
BEST ANSWER: Pen height will depend on your dogs jumping abilities and urges to chase. I prefer the 48 in pens for my Cavaliers.
Can multiple pens be hooked together to make larger pens?
Carol W on Feb 20, 2014
BEST ANSWER: I see no problem connecting multiple pens together. I configured a single cage to suit my needs by rearranging the individual sections so the door was where I wanted it to be. I didn't use it in the traditional method. I attached each end of the pen to the sides of a kennel. This way the dog has more than just his kennel in which to move around. It's like a kennel with an attached pen. I used small caribiners to attach the the ends of the pen to each of the front corners of the kennel. It works great and the caribiners are much stronger than the regular clips which hold the pen together.
Is this pen good enough so that a Boston Terrier cannot jump over the fences? Also, does this pin have stakes to drive into the ground to hold in place?
A shopper on Aug 19, 2013
BEST ANSWER: The 48" is definitely tall enough for a Terrier. I have a male Yellow Labrador who is a puppy. He's currently about 37 pounds and wouldn't have a chance of jumping out of the pen. Ground anchors are included but you may want to buy some larger ones in the camping department of Walmart or Target. The larger anchors, intended for use with tents, would definitely keep the pen in place.
I pet sit small dogs from 0-50 lbs which is the best size to use?
Julie p on Oct 16, 2015
BEST ANSWER: It depends on how much space you will need.
Can you purchase extra panels instead of a total other set?
snagel on Mar 18, 2015
BEST ANSWER: Hi. Currently we do not carry extra panels for this exercise pen. You may be able to contact the manufacturer to see if and where they have panels for sale separately. Hope this helps!
Can it be used outdoors?
A shopper on Mar 10, 2017
BEST ANSWER: I have used exercise pens outdoors for about 10 years. There is very little rust. The first thing to rust were the harco clips. I currently have five Cavaliers and the pens work wonderful. At my home I have my patio fenced from the rest of the yard with the exercise pens. At my seasonal campground site I use them to fence an area near the camper so the girls can be safe. LOVE the gate, all I need to do is step over the bottom piece to go in and out. They are great for pet safety. Just remember the kiddos still need to be watched.

What is the best size for a full grown Shiba inu to have room to run around in?
Yessy on May 7, 2016
BEST ANSWER: There are 8 panels each 2 foot wide. They can be configured anyway you like. I use a total of 8 exercise pens that I fasten together. I'm a frequent camerp and use them to form an enclosed area around my motorhome. I place 2-3 pens on the side of the motor home to prevent my furkids from getting under the motorhome. The rest I run out a few panels than the rest I run parallel to the motorhome. My fur kids have plenty of room, with room for a small picnic table and some chairs.I use no leashes to prevent them getting tangled. I have 5 Cavalier King Charles Spaniels. I choice the 48 inches to help,prevent humans from reaching into the pened area to pet the furkids. I also use these at my home to enclose my patio. I love them and the job they do to contain my furkids.
is this cage good for 3 rats a 30 inch one?
A shopper on Jan 4, 2016
BEST ANSWER: Not sure what your rats are able to squeeze through, but the majority of the pens openings are about 1 1/2 inches wide by 6 inches high. And couldn't they just climb up over the top? Hope this info helps!

What is the difference between the Midwest Exercise Pen with door and the Life Stages Exercise Pen with Max Lock door?
Can I disconnect the panels so I can attach the ends to a wall?
Barbara B on Apr 3, 2016
BEST ANSWER: The Max Lock door has about a 6 inch step over for easy enter/ exit for humans and furkids. Other exercise pens have a small door that only accomadates the dog going in and out. The clips can be removed on the panels but I've had no success in finding replacements. I use plastic ties but they need replaced as they wear out from the weather.
Is there a topper or cover that I can buy to use as a sun blocker that will FIT this unit ?
What is the overall dimension of the pen if set up as an octagon48x48?
A shopper on Jul 15, 2015
BEST ANSWER: The only cover we carry for this item , 110143 - MidWest Dog Kennel Top , specifies that it only fits when pen is set up as a 4' X 4' square .
