Lulu's ain't cheap, but unlike most of overpriced Vegas, it's worth the cost of admission. I brought in my Australian Shepherd for a summer trim of his undercoat. I wasn't expecting anything spectacular--just a trim to reduce shedding. But they did an exceptional job.
I've taken the dog over to Petco before for a quick trim and they do an okay job. I never even considered that there could be a better hair cut for a dog. I just assumed that Lulu's would do the same job as Petco and I'd be supporting a local place.
But the dog looked amazing after the trim. He panted less, was able to be outside longer and just looked better (not to mention that the hygienic trim makes sure nothing gets caught in the dog's fur when he goes to the bathroom). Three months later, the dog is still shedding less and still looking more comfortable in the Vegas heat.
Finally, the staff is great with pups. I've taken a second dog over there--a problem dog who dislikes other dogs and can't stand having his nails trimmed. Five minutes later, my problem dog and I were on the way out the door with trimmed nails and no drama.
