This pet stroller is not worth the money.  The wheels are plastic and steering this takes both hands and strength.  If you are walking on a path that is bumpy, you need both hands on the handle and muscle to keep the stroller straight.  The only reason I have not returned this is because my dog has a heart condition.  We bought this stroller when our other stroller that we had for 9 years finally broke.  
After one walk with this stroller, I found a Pet Gear stroller and ordered it.  I will have to use this Wayfair stroller until the other arrives in about 3 weeks ... it is going to be a long 3 weeks ...
Do not waste your money on this.  I am very disappointed with this purchase.  This isn't worth the money at all.
