Marlenia helped me train two very different, challenging dogs. She spent half a day with me at Town Lake screening candidates, at the end of which I took home Sparky, who has been an excellent dog for me. Her experience and insight have proven extremely reliable again and again. She has an effective technique for everything and no end of affordable advice to spare you a $20 trip to the pet store. She's my first stop whenever I have a dog issue, and she's always responsive by phone and e-mail. I recommend her for help with any dog.
