Testimonials
“Tessie and big brother Big Papi love the crew at A-1 Critter Sitters. We have used them for over 10 years and have always been reliable and personable. Our 2 pups and 2 cats are always in good hands when we have them take care of our fur babies when we are away!!”
– Earl Truland
“A 1 Critter Sitters is absolutely fantastic, and I cannot recommend the service highly enough. Theresa has been sitting for our Jack Russell for over five years, and there is no one that I would trust more to care for our girl.”
– Sarah Glass
“We’ve used A-1 Critter Sitters for over ten years and find them very reliable. They are animal owners themselves and understand that different pets have different needs. They’re always willing to accommodate any special needs or instructions we might have. Highly recommended.”
– Lloyd Becker
About the Trainer
A 1 Critter Sitters and Training is a dog training and pet care service based in Riverhead, NY, offering one-on-one in-home dog training to help families train their dogs to behave calmly at outdoor events. Founded in 2020, the business builds on 28+ years of pet sitting experience and uses a unique Canine Life And Social Skills (C.L.A.S.S.) program that guides dogs and owners through progressive training levels—from beginner to advanced. Training is delivered in the client’s home, minimizing stress for the dog and allowing the owner to actively participate as the primary trainer. They also offer training walks (30–45 minutes) separate from potty breaks, pet sitting, dog walking, and cat care—all provided in the client’s home. Their trainer, Theresa Cahill, is certified by Animal Behavior College and PENN Foster University in dog and cat training, grooming, and pet first aid/CPR.
They serve families with puppies, rescues, and adult dogs, focusing on real-life socialization and behavior for everyday situations. Their services are tailored for pet owners who travel frequently and want their pets to remain comfortable at home rather than in kennels. They also care for farm animals, including horses, goats, and cows, making them uniquely versatile for multi-pet households.
