The Dalmatians

Sharon first become interested in positive reinforcement training (having previously been a traditional trainer) when she wanted to ensure her Dalmatian pup Jasper would be well behaved without having to use harsh methods. The use of positive reinforcement meant Jasper was always willing to have a go and try new things. It was a joy to watch how much he loved training.

Currently Sharon and her husband share their home with two Dalmatians but Sharon has had a variety of dogs over the years. Her previous dogs included a Terrier/Llasho Apso cross  (who used to smile like a Dalmatian) , German Shepherd Dogs, a Labrador, a Kelpie cross and several rescue mixed breeds.

If ever Sharon needed confirmation that positive reinforcement training brings results her second Dalmatian Pippa proved how powerful this method of training can be. Pippa is a ‘special needs’ dog who suffers from anxiety related aggression. This aggression manifests itself in the form of resource guarding (the dog protects things it sees as valuable such as food, toys, space and people). By the age of 7mths one specialist recommendation was to have Pippa euthanised. Sharon refused to give up on this feisty beautiful Dalmatian and with the help of the Veterinary Behaviourist at Sydney Animal Behaviour Service (SABS) Pippa ha made amazing progress. The journey has not always been easy but the joy of seeing Pippa’s improvements have been truly inspiring. In one instance she has gone from not being able to be touched when resting to rolling over for a tummy scratch. Sharon feels very lucky to have a special needs dog that has provided the most wonderful learning experiences.
