Roz (Top Dog)

Roz is the owner and managing director of the Mutty Professor. She lives on the outskirts of Bristol with her partner, two cats and three dogs.

Roz grew up in the rural Herefordshire countryside surrounded by animals.

After a decade in retail management she became frustrated at being couped up indoors and left to start The Mutty Professor in 2010.
The dog walking side of the business evolved into dog training and behaviour, and seven years on Roz is now one of Bristol’s most recommended and respected trainers who works alongside other positive reinforcement trainers.

She has a keen interest in helping to rehabilitate rescue dogs with issues and has volunteered at a spanish rescue shelter four times.

More recently Roz is taking steps towards training other species of animals and has had the opportunity to train lions, Rhinos, Polar Bears, Wolves and Chickens!
She is hoping to expand on this experience and improve the welfare of animals in captivity by using positive reinforcement training to help reduce stress in their day to day life as well as teaching them to actively participate in their own healthcare (vet treatment).

In her spare time she is a keen indoor and outdoor sport climber.

This attitude towards the well being of dogs along with her enthusiasm impressed Roz and she has since been a reliable and valued team member.

Some clients have reported a huge improvement in their dog’s behaviour since Karla took over their solo walks- music to Roz’s ears!

Denzel (Big, Ginger Biscuit)

Anyone who meets Denzel loves him. He’s quite a character.

Brought over from Spain in October 2010 by the rescue charity SOS Animals, I adopted Denzel (previously called Bubbles!!) in November 2010.

He spent the first three years of his life chained up in the sweltering southern Spain heat and was abused by his owners. He was then rescued and spent a year and a half in the shelter before being sent over to the UK for fostering. I spotted him on a dogs blog and decided he was the dog for me. Four days later I drove up to Birmingham and came back with him.

Considering his past he is an asset to the team. He’s very laid back and his calm demeanor has a great influence on all the dogs. He does join in with some play but more often takes a back seat or acts as a referree,  intervening with dogs that are being rude or getting over the top without having to be too forceful.

Denzel semi-retired during the summer of 2013 after battling cancer. After lots of alternative and complementary therapies he is getting back on track. He rarely joins in on social walks now, but will sometimes do the occassional social session.

Letov (The Dogarus)

Letov is Roz’s second rescue. Brought over from the same rescue shelter in Spain as Denzel, Leto is very loyal and never strays too far. He can be quite aloof and not very dog-interactive on walks and as such is an excellent dog to have when it comes to teaching youngsters manners and that not all dogs are play objects, as well as building up the confidence in shy dogs. He has the most fantastic way of communicating with other dogs.

Rescued as a puppy amongst a litter of five, he was overlooked for four years long after all his siblings were adopted. Despite having a (non contagious) incurable disease (it’s a bit like malaria), Letov is healthy, full of beans and loves life. He is a great advert for how all rescue dogs that have health issues are capable of being the dog of your dreams.

Leto helps me with teaching aggressive dogs how to communicate better through calm and relaxed parallel walking sessions and social walks. He has helped many dogs overcome their fears and learn to communicate and behave appropriately.

Sadly Leto passed away on 3rd of August 2017 due to a complicated illness. During his six years with Roz he helped rehabilitate a lot of dogs.
He will be dearly missed every day.

Kanita (Feral Cole)

Once known simply as K14, Kanita is by far my most extreme rescue case.

Once a feral/stray village dog in Thailand, Kanita was stolen and became one of a thousand dogs seized by the Thai police when they were intercepted en route to Vietnam- to be turned into meat. The meat trade is illegal in Thailand and so the black market smuggles them over to Vietnam where eating dog meat is still legal. This massive group of dogs were held temporarily in a cattle holding area while volunteers got to work feeding them, giving them codes for identification and taking photos for all the waiting rescue charities. A charity called K9 Angels selected ten dogs, K14 being the first. Once selected they started to prepare them to be fostered in Bangkok and during this time Kanita tested positive for the deadly distemper disease. Fortunately as the week passed she showed no symptoms, and two weeks later she was recovering from ordeal in her foster home where she eventually completed her quarantine.

She arrived in the UK on September the 13th 2012 and we collected her from London and brought her home. She recovered from her journey quickly, settled into group walks and is now my main teacher for learning about canine body language. As an ex feral street dog some of her signals are very different to any other dog I’ve known, and I find it a joy to watch her.
Kanita also helps out on the last stages of social walks for reactive dogs and puppies.
