first off i know not taking your dog outside is wrong...but here in massachusetts its very cold outside and snow randomly with all that black ice outside make not wanna go outside often with all that black ice...so ive been looking up potty patches...Ive been using the potty patch with the grass.And somehow it came to me that is why her paw might b red due to bacterial.But the UGODOG and WIZDOG dont use fake grasses,it use a later of plastic with cubed space allowing the urine to pass through and easier to clease by rinsing...But what i really wanna ask yall Bully Owners if anyone have experience between the 2.please help me decide between the 2 till the coldness pass so i can take her outside more often...also i would like to ask,do you guys approve of this http://www.radiofence.com/products/Snoozer-Ortho-Lounger-Pet-Bed.html so i can use in her crate when she goes to sleep or when shes unattended.Other then that she would be on the bed with us
