I love dogs and I live in Wassenaar.
I volunteer every Wednesday afternoon as dog walker by the animal shelter Dierentehuis Stevenshage in Leiden! Do you want to bring your dog there when you are away for holiday? Otherwise I'm available on Wednesday, Saturday and Sunday to just focus on your dog. I can drive to your place and visit your dog by your house, and have a walk to his/her favorite park. Just sitting in the garden or your living room is also fine of course.

I'm used to both active young dogs and chill senior ones.

Other days I work office hours, so it might also be possible to arrange something, especially if in the early morning or in the evening.
Contact me for any additional information!
I would be happy to meet you and your dog, and see if we can have a great time together!
