I am a pet lover - dogs as well as cats. Lived my whole life around and caring for my dogs back home in Latvia - playing and exercising them, physically as well as mentally. Back home I even went through dog school with my German Shepherd and trained our puppy on my own. Here in Leiden I would prefer small to middle size dogs, just because in case of per boarding I believe my apartment would be a bit too small for a large dog.
All my experience with dogs does not take away from my love of other pets like cats - in facts I am the godmother of 2 cats that my friend owns.
In general, I am an animal lover that believes that each pet is different with their own personality that needs to be stimulated. :)
