if it where me here's what i would do, if you do not want to investing the time and money into ceramic tile i would just paint it with an epoxy reinforced type paint, i used that in my laundry room and at least 5 dogs pass through there 4 times a day for the last 5 years and it seems to hold up very well, only problem is if you paint and down the road you decide to go ceramic tile you will have to strip off the paint, major pain in the a...s, i did a 19 x 15 room in my basement that had that industrial carpet with the black rubber backing glued to the cement floor, i had to pull the rug scrape off all the foam backing that was stuck to the floor and then use a paint stripper to remove what glue and backing that was left on the floor to get it to be clean concrete again so that the tiles would have something clean to adhere to, took me about a week to remove all the glue, major pain in the a...s, but worth it in the end as it looks like the day i installed it many years ago and thats with an average of 5 boxers on it 24-7 lol, i think i would just paint it as it will look nicer than plain concrete and if you ever decide to sell the house down the road you could throw on another fresh coat of paint or carpet over the paint.
