Theo De Silva, dog trainer

Lifelong animal lover.
Practical trainer.

Hi, I'm Theo. I got into dog training after a difficult encounter with a stranger's dog made me curious about why dogs behave the way they do, and what we can actually do about it.

Since then, I've worked with stray dogs in Sri Lanka, spent time in kennels and rescue centres, completed numerous training courses and workshops, and run my own dog walking business alongside Desilva Dogs. I also look after three dogs of my own.

For over 8 years I've helped dogs and owners work through all kinds of challenges - always with patience, consistency, and a genuine love of what I do.

Real dogs. Real results.

Don't just take my word for it - here's what some of the owners I've worked with have to say.

★★★★★

"Theo has helped me immensely training my rescue dog Axa from Romania who was reactive to other dogs. He helped me with a program of gentle socialising, positive reinforcement and consistent training. Today Axa is a well behaved dog who enjoys her group walks and I would highly recommend Desilva Dogs for any training required with his own dogs displaying exemplary discipline."

"My dog was unusually anxious for a retriever, and was in the habit of overreacting to other dogs, particularly if they were in close proximity and on leads. On the road he was worse than in the open park, and would quite often lunge out and appear quite aggressive as he tried to protect himself. As a result of Theo progressively exposing him to more challenging situations, my dog gradually gained confidence in walking close to, and then approaching other dogs. Theo gave very detailed feedback after every session and sent me frequent videos illustrating my dogs progress. Theo stressed the need for consistency throughout training across all handlers."

"Theo is a marvellous dog walker and trainer. I've personally hired Theo to walk my friend's Chihuahua when she was out of town. I was house-sitting for my friend and watching her dog Coco. Who most of the time can be a bit needy and misbehaved unless she's really tired or with her owner. so watching her was such a difficult task for me. I contacted Theo to help me with Coco, and he was able to train her to walk with his pack. Coco is generally aggressive towards other dogs, barks quite sharply and is terrified to be around bigger dogs. However, Theo helped her break out of her shell, made her more sociable with bigger dogs (including his wolf dogs!!). Overall, I thought that for the price, his services were extremely high quality and professional. Definitely will be booking him again when I get my own dog. He's trained in dog psychology so he's got loads of scientific knowledge on behavioural training, so dude knows what he's doing."

"I had an over friendly, excitable, hyperactive German shepherd dog. SOX I had tried other trainers from him being a puppy and older. None worked and seem to work the same way but failed to help me get control over him and own a stress free dog, who was confident around people and other dogs. I used to walk him around 3am so he did not get so over excited to play if meeting other dogs that he would lunge and bark at them. I was so glad that Theo was recommended to me and after I contacted him we were accepted for an assessment. At the assessment I really felt listened to right from the start as Theo took the time to learn all he could about Sox before he even met him. All our training was tailored for his needs and also around my disabilities which was at times very challenging. Theo was firm, persistent but very encouraging which we both needed as I was waiting to fail, which would of course not help. I felt not only my dog has benefited but I have too. I have learnt so much about him and myself. I am now the PROUD owner of that confident, calm dog who I can walk anywhere, anytime even in day light. He can be on or off lead but I know I have control as he will now listen to me and follow my directions when asked. Our training is on going as we can now discover different places and situations but he is loving the walks and living a proper doggy life, which he never had before. I can not recommend and thank Theo enough for giving this to Sox and the confidence to me also to believe my dogs behaviour can change following his instructions. Theo gives a great structured steady training and will also help between sessions if any issues occur, which I had loads at the beginning. Thank you and a big woof from Sox."
