Organised by his local dog walking community with the help of the City of Wanneroo, the tree will serve as a tribute for Roy, who was recently diagnosed with cancer and told he had limited time.
Roy has struggled since receiving the news and said the dogs and owners were the only thing that �really kept him going�.
Genevieve Jarvis, a member of the dog walking group who meet each afternoon, helped organise the April 2 planting.
�Roy cried tears of joy on the day that it was planted. It was the first time I had ever seen tears roll down his face,� Genevieve said.
�He has not stopped talking about the tree and goes to see how it is progressing on a daily basis.�
Genevieve said the close-knit community could sometimes attract up to 40 dogs that would play together at the park.
�It is a very unique dog group; I don�t believe that there would be any other like it out there,� she said.
She said Roy was part of the RAOB Society, served for Driver Reviver and Safer WA and was in Neighbourhood Watch for 12 years.
�He has also assisted with raising funds for Princess Margaret Hospital, Charles Gairdner, the Heart Foundation, blood transfusion, heart research and many others,� she said.
�Roy is a valued member of the dog walking group and has always been a very kind, humorous individual.�
