If you haven't done already, you really must check out the new dog grooming salon, called Rita's Place in Amsterdam city centre. The place is named after the owner's Basset hound. Excellent service from a Brit called Tara.
Lots of top-end treats on sale too, like dog beds, leads, organic dog foods.
