Roz (Top Dog)

Roz is the owner and managing director of the Mutty Professor Ltd. She lives on the outskirts of Bristol with her partner, their three 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. Eight years on Roz is one of Bristol’s most recommended and respected trainers who works with and alongside other positive reinforcement trainers. She also presents seminars in the UK and abroad on training and behaviour.

She has a keen interest in training voluntary veterinary behaviours. She is also passionate about rehabilitating rescue dogs 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, Porcupine, Foxes, Raccoons, Rhinos, Polar Bears, Wolves and Chickens!
Roz is passionate about improving the welfare of animals in captivity. Positive reinforcement training can 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 rock climber.

Denzel (Big, Ginger Biscuit)

Anyone who meets Denzel loves him. He’s quite a character. Brought over from Spain in October 2010, Roz 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. Roz spotted him on a dogs blog and decided he was the dog for her.

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.

Denzel semi-retired during the summer of 2013 after battling cancer. At nearly 13 years of age he’s now fully retired bar the odd social walk or session when he’s having a really good day and Roz feels he can handle it.

Kanita (Feral Cole)

Once known simply as K14, Kanita is by far Roz’s most extreme rescue case. Once a feral/stray village dog in Thailand, Kanita was one of a thousand dogs seized by the Thai police who intercepted them en route to Vietnam- to be turned into meat. The meat trade is illegal in Thailand and dogs are smuggled to neighboring countries. This huge 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. 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 on canine body language. As an ex feral street dog some of her signals are quite different to any other dog I’ve known and I find it a joy to watch her.
Kanita is sensitive to handling and has helped Roz develop her voluntary vet behaviours training. She also helps out on the last stages of social walks for reactive dogs and puppies.

Roo (The Rooligan, Rhubarb, Rubicon Mango)

Roo as adopted by Roz April 2017 after his loving owners decided he wasn’t coping with their toddler.
Roo is loving life as a semi-working Collie. He helps out with dog-dog sessions as well helping Roz film training tutorials.
He’s an exceptionally friendly chap and a great ambassador for Border Collies.

Leto (The Dogarus)

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 on dog-dog sessions.  He was truly one of a kind and was taken away too soon at 10 years of age.
He will be dearly missed every day.
