Client Feedback Group 5592



Matt, Aaron, and the team are wonderful with my rescue puppy and he loves going to daycare. He's become wonderfully socialised since going to Bark & Birch twice a week -- it's helped him with all facets of his confidence. He was terrified of everything when he first arrived from Bulgaria and now playing with other dogs is his absolute favourite thing! It's also incredibly convenient that he's picked up from home and dropped off in the evening so I can focus on work. 


5 121 basic training

Elly was absolutely amazing with our puppy Poncho. We booked 5 one-on-one training sessions so that Poncho could learn key skills and the basics and she was brilliant. We would have been lost without her and she made the sessions really fun for all of us. Poncho loved her too. Thank you for a reliable, professional and fun service Elly!



Diego absolutely loves when the doggy taxi arrives in the morning to take him to the daycare. He has attended daycare with B&B for the past 3 months. We appreciate the daily videos and having a tired and happy spaniel coming home at the end if the day!! Thx team, we will definitely continue to use your services.


2 week residential dog training

My 10 week old American Bully puppy was very bitey, lacked focus and needed some intense basic training. Bark & Birch looked after her from the offset, sent me videos and kept me fully updated on her progress. She returned after 2 weeks much calmer, much less nippey and responding well to basic commands. The handover was really useful and insightful. Absolutely brilliant service, highly recommend! Thank you Bark & Birch!!


8 121 basic and advanced

I purchased a course of 8 obedience training sessions. Good value for money, trainer comes to you , 1 on 1. Our trainer Michaela is very good, as first time dog owners, we had many questions which Michaela happily answered them all, not only in our session but even on whats app for FREE! she also helped us to solve a few minor issues we had with our dog, some knowledge that wasn't in the dog training books or videos that i had read or watched.


3 week advanced residential dog training

I highly recommend Megan! She trained our dog in a 3-week, one-on-one Programme. She designed a training routine that aligned with my expectations and requirements. Megan was very responsive - I spoke to her on a daily basis, and she also shared plenty of pictures and videos on training sessions. I liked the fact that she only uses positive reinforcement to train dogs and makes sure to give them plenty of exercise and rest every day.


5 121 basic training

We have just finished out block of 5 training sessions with Bea, she was remarkable, giving us fantastic ideas to keep our German shepherd pup engaged during her training. Mica's recall is certainly a lot better, she walks perfectly on the lead. Our pup is always excited to see Bea, and knows she is going to have a fun training session . I've just booked for more sessions to perfect her recall


3 week advanced residential dog training

Bark & Birch has been great with our new cane corso. John has been very professional and responsive. I was updated daily with videos of the training progress. Definitely amazing in this sector! Looking forward to sending our dog away for protection training in the next couple of months.


2 week basic obedience residential dog training

Responsive and tailored service. Really understanding of mine and my dog's needs. On walks, my mini dachshund would bark uncontrollably at everyone in sight. Now he is very manageable on walks and will not bark if told so. I love how they send pictures of what my dog is up to whilst in their care :)

Eva & Bruno


The team at Bark & Birch gave me all the trust I needed to help me with my french bulldog Bruno. I was looking for an intensive training or rehabilitation Programme so he could feel comfortable around other dogs. They did a great job by taking care of him and showing me video updates. After all, I feel more relaxed when taking Bruno for a walk and teaching him being near dogs. I trust their service and I recommend you all to contact them.
