laminate or vinyl flooring?

I vote for laminate. I have it in my kitchen and love it. So easy to clean and easy to walk on. It's the more current choice especially if you ever plan on resale.

laminate over vinyl. I think it looks better and cleans up very easily. BUT, if there will be pee, I'd be concerned about the pee seeping through the seams of the laminate and onto the subfloor. at least with solid vinyl, no seams for pee to get through. it's not the most attractive surface but at least you have a seamless option.

I installed vinyl in my senior living building. It is beautiful. Had I seen this before I put in my laminate I would have gone with it. It hold up great.

I agree with @busypea - especially if you might switch it out later. It's cheap and looks good. We put vinyl plank down in a rental - it's held up great in very rough conditions. It "looks" wood like - depending on the pattern/brand. Depending on what you put it on will determine how much it "feels" like would. We put some on a cement slab - it's really too hard to fool anyone - especially barefoot. The ones we put over plywood - feels like wood - honestly half the renters or prospective renters thought it was wood. Laminate + liquid = disaster.

Beautiful and much better for resale than laminate or vinyl.

I think they're a great choice if you know you want to go in that direction - and don't mind the hard surface.  The OP indicated that they might want a different option after their elderly dog is no longer peeing on the floor.  I wouldn't go through the expense of tiling and especially the pain in removing them to put in something else as a temporary solution.  

Truly depends on where you are. In a warm climate, sure. Around here, tile is profoundly unpopular because it's just too cold. Even with radiant in-floor heat, it's just not desirable. I don't remember the last time I saw tile anywhere but bathrooms around here. 

Not to mention pee can pretty easily absorb into grout with persistently smelly results. 

I put this "stone" look of this COREtec Plus flooring last year in our kitchen.

I am very, very happy with it.  I hope to use it elsewhere in the house, but using the wood floor styles in other rooms.

I would say go to an actual flooring place (not Home Depot or Lowes) and talk to someone about your options for your specific situation. Flooring is constantly improving so you might be surprised by what your best option is. When MIL was still alive, she lifted the cabin and added a walkout basement. Knowing that we have dogs that are constantly in and out of the lake and that we would be frequenting that space quite often, that's what we did before we made a decision.

We ended up choosing a heavy duty laminate flooring and in the seven or so years it's been in there we haven't had a single problem. That floor has been wet for days on end when we're there, has been peed on, puked on, wet swimsuits dripping on it, it's been mopped endlessly, etc. without any issues at all. It has held up to dog toenails running on it, wheeled coolers being rolled over it and furniture being moved around. It looks great and has held up exceptionally well.

Another vinyl plank here too. I've had people "feel" it too. It does have the grain of wood in it which makes it more realistic. It's almost too perfect because there are no scratches like my real wood floors in the bedroom. I have 2 dogs that chase through here, had a water dish dumped with no issues. Mine's about 4 years old and still looks good did the kitchen, dining room, halls and powder room.

For those of you with the vinyl planks, what brand did you buy?

We put down vinyl planks in our very high-traffic bonus room. People come in and out all day long directly from outside, so lots of wet feet. Plus we have 4 kids who spill things a lot. It's been very practical and is holding up really well (it's been a year). No one has guessed that it's vinyl - people think it's laminate. Anyway, I was not excited about getting it. Vinyl just sounded cheap to me. But it really has turned out to be the best thing.

Ours looks like the one that busypea posted. It's from Lumber Liquidators and we installed it ourselves. (We bought it before that whole controversy with Lumber Liquidators.)
