Thank you very much.

Working with Mark at On the Fly pet sitting has been so easy and convenient. Mark is incredibly easy-going and it is easy to tell that he has a genuine love for animals. I have a 4 month old puppy and a five year old dog who have very different needs. I find watching my puppy pretty challenging sometimes but it is never an issue for Mark! My dogs love his yard and I feel like they are getting their own little vacation when I'm out of town. Another huge plus is the price - I've normally paid around $55 for each dog, but Mark's fee's provide a huge cost savings for me. I highly recommend using Mark's services if you are going out of town and want your dog to be comfortable and happy!

Mark has been a Godsend to me and my two dogs. They are older and had lost their 'man'. Mark has been the best replacement for their loved 'man' and has made both of them happier, more well-adjusted and infinitely more playful.

Finding Mark and this service has allowed me the peace of mind to travel again knowing that he'll take care of them as if they belonged to him.  
I am beyond delighted with this man and the service he provides my family.

We used On The Fly Pet Sitting recently when we were out of town. Mark and his family provided our dog Toby with amazing care and attention 24/7.. They took him on hikes, which he really enjoyed, and generally provided him with lots of love and play. Toby is a member of our family and we are usually anxious when we leave him but we could see that he he was having such a good time with Mark and his family that we were able to enjoy ourselves. I absolutely recommend On the Fly Pet Sitting and will be using them again shortly. I would not want to leave my dog with anyone else.

Mark created a great second home for our dog, Willy, over the long weekend. The team took care of our boy and brought him not only to the park, but on a hike and swimming. The only bad part was, we weren’t sure if Willy would want to come home with us after having such a fun time. We also loved getting a text photo update and hearing how lovingly Willy was welcomed at Mark’s house. We highly recommend On the Fly other dog lovers!

We were thrilled with the treatment Finn received and highly recommend Mark as a reliable  and caring pet sitter.  Finn let us know he enjoyed himself as well when he was reluctant to leave when it was time to pick him up.

The benefit of working from home is that your dog gets to be with you 24/7.  The downside is that when you do need to board him, he is anxious, scared and completely unfamiliar with being placed in a kennel overnight.  This tends to make for a nightmare experience both for our dog and the big brand pet boarding services.

I recently used On the Fly Pet Sitting and was amazed by the experience.  As a boutique pet sitting service, the entire process was personalized to the needs of our dog.  Mark was kind, extraordinarily communicative about his hands on process, and most importantly genuinely concerned about the experience and care of our pet.  Rather than being one dog of 20, our lab was given individual attention for the duration of his stay.  From walks on the Cocheco, to playtime in the back yard with Mark, Otter was treated as if he was Mark's own dog. Upon pick up, we found our pet to be happy, tail wagging, and believe it or not, a little reluctant to leave.

On the Fly Pet Sitting will be our go to play to board our pets in the future.  Incredible value, hands on and caring experience.  Strongly recommended.

We are so happy we found Mark Foley and On The Fly Per Sitting! Once we adopted our sweet Laila we knew she would need lots of love and attention, Mark has immensely helped to facilitate the care she needs when we are not able. He has always been reliable, easy going, and caring with Laila. She is so excited to see him every time, it makes my heart happy.

I cannot say enough good things about Mark! He took care of my shepherd Maya who is a difficult dog and usually very leery and sometimes aggressive of new people but within seconds she licked Mark's face. His beautiful calm energy transfers onto the animals and Maya is living proof of it! Definitely my favorite place for my animals!

Mark is great. Flexible, relaxed, wonderful with the dogs and really gets them out for a good romp which I really appreciate!

Mark is such a great resource. He is a relaxed guy- so he puts our pup MIRA at ease right away. It is so nice to pick her up and know how well she was cared for. No post kennel crazy here. She is at home with Mark and he will he our go-to guy when we go away!
Thanks Mark!

Mark has been taking care of our 9 year old Chihuahua, named Peanut.  Everything is going very well.  Peanut is a normal dog, but he has a few special needs.  He has had cervical spine surgery. He can be very lovable, but he also can be a difficult dog.  We hired Mark as a dog walker three days per week to help break up Peanut's day while we work.  Mark is mellow, easy to get along with, and handles Peanut's special needs with ease.  Mark has a flexible schedule, responds immediately to our text/calls, and is very reliable. We are very happy to have found Mark, and look forward to working with him in the future.

I have known Mark for about 10 years.  We have fished, hung-out, and he has watched (fed-watered) my chickens.  Now he's watching our our dog and cat.  I have a huge, Greater Swiss Mountain Dog, and she's always got along with Mark.  If Mark says he'll be there, he will, and he'll do a great job. Don't hesitate to trust your furry kids with Mark.

We were Mark's first 'cat' client and we were so very impressed with his professionalism and love for animals. He was very conscientious and did a wonderful job of getting to know all six of our cats before we went on vacation. Two of our cats walk well on a harness, he tackled that with ease! We came home to a happy cat household. I would recommend Mark Foley to anyone that wants the best for their pets while they are away.

I highly recommended the services provided by On The Fly Pet Sitting.  My dog can be difficult at times, she barks a lot, chases cars and doesn't get along very well with other dogs. Asking someone to take care of her can be a challenge. As I searched I found Mark's blog on the Internet. After reading his blog and meeting with him I knew she would be in very caring and competent hands while I was away on vacation. Mark got her, like we get her. He cared for our dog as if she were his own. 


I cannot express how much I appreciate his services. I will not hesitate to call him the next time I need a dog sitter.  I would highly recommend him to anyone.

Thanks again for taking such good care of Sadie for us.

Let me start by saying that Mark Foley with On The Fly Pet Sitting provides consummate professional care for your pet and I would highly recommend his service to any of our friends or family.

We have a small dog, Cobie, who is almost 10 years old and has special needs.  Our dog had a severe illness a year ago and as a result was diagnosed with diabetes and requires particular care.  He is on a regimented schedule of feedings, insulin injections, and exercise, so his supervision is more complicated than the average pet.

We recently decided to take an extended vacation overseas and it was the first time we left the dog since he became ill.  Needless to say, we were feeling anxious about handing over that care to someone else for two weeks. 

We didn’t need to worry with Mark on the job…

Mark is, in a word, amazing.  He loves animals and is trustworthy, conscientious, responsible, and kind.  Although he already has certifications in pet CPR and first aid, he went the extra step and researched canine diabetes and is a pro at the injections/medication administrations. We were truly impressed because it was difficult for us to get the hang of regulating our dog and I’m a nurse.

We flew Mark to Arizona from New Hampshire and he house sat for us as well.  At the conclusion of our travels we arrived home to find the dog and house in perfect shape.  I don’t think the dog even missed us! Cobie and Mark formed a special bond and it was a wonderful experience for us all.

Thanks, Mark!  We loved having you here and look forward to the next time we get to see you.  Cobie misses his morning strolls with you and is still checking your room to see if he can come in for a cuddle or a treat.
If you are looking for someone who will love your pet(s) and treat them as well as you do then you’ve found that person in Mark Foley.
