I have two Pet Gear Pet Strollers. They are very well made and wonderful to have. I like to walk my dog, but a stroller can keep them safe from other dogs, getting stepped on in crowds, and bad weather.
I use my AT3 every day for my walks using a Strollometer to keep track of time and miles. The weather cover keeps off wind and cold. The zippered screen lets the dog be free inside and safe from people grabbing at them without permission. If it is really cold, I put in a warmie (rice-filled sock heated in microwave for 2 minutes wrapped in a pillow case).
I also have the Sportster. It is smaller and easier for shopping or traveling. My dog uses it every day in the house as her little bed/perch. People will roll their eyes, but you see them more and more all the time.
I found the best price on ebay from Pet Adventure Outlet. They also have a website
petadventureoutlet pet gear products. It does not always come up in the search, but you can type in "pet gear AT3" and it will come up. They list it for $122.95 with $18.50 shipping. Total is $141.45.
Let us all know when you get one and which model and color you picked out. Let your pup sit in it in the house and play in the basket underneith (put in treats or toys) and they will claim it for their own.
Have fun!
