I've been using these FRONTLINE underpads for about a month now, and they've become my go-to solution for multiple messy situations. The 23x36 size is perfect - it's like getting a runway's worth of coverage compared to those dinky square pads.
For my elderly dog who has occasional accidents, these pads catch about 90% of the mess. They're not the most absorbent pads on earth (I did see some minor edge leakage once when he really let loose), but for the price, they do a decent job. The blue backing is genius - no more guessing which side goes up during those bleary-eyed 3am changes.
Unexpected bonus? These became lifesavers during potty training my toddler. That extra length means even when she does her signature 'alligator death roll' during diaper changes, we stay protected. I keep one permanently on the changing table now - way easier than washing covers constantly.
The thinness worried me at first, but turns out it's perfect for my small dog's daytime pee breaks. She's only 12lbs though - I wouldn't trust these with a Great Dane-sized bladder. For travel or temporary use, they're fantastic since you can just roll up and toss the whole mess.
They won't completely mask urine smells like premium pads, but for quick changes and moderate accidents, these strike a good balance between cost and functionality. Not luxury bedding by any means, but solid workhorses for everyday mess management.
