My trainer, Sarah, was highly knowledgeable and shared many tips over our 5-lesson private lesson package that helped my Shih Tzu gain confidence around other dogs after he was bitten by a pitbull this spring. She was accommodating and would allow me to bring my friends' dog along or one of her dog acquaintances to change up the environment in between lessons. I do wish that there would be some kind of discounted follow-up package for dogs who have attended private lessons and need more group environment stimulation (they charge a flat fee of $45 to bring your small dog to one group walk session, which can be costly as I have already paid around $700 for 5-lesson package), which would help me more accessibly reinforce the tips we've learned over time. Other than that, my experience with Summit was overall positive and was worth the investment.
