Japanese Spitz vs Portuguese Water Dog

If you’re drawn to the Japanese Spitz, you’re likely living in an apartment, maybe new to dog ownership, and want a loyal, affectionate little buddy who’s happy napping on your sweater or playing gently with kids. They’re adaptable and surprisingly sturdy for their size, but don’t be fooled by that white coat. it sheds year-round, and you’ll see snot marks on the fur if they have chronic runny eyes, which some do. They’re sweet, but not particularly driven. You’ll need to bring the energy. The Portuguese Water Dog? This dog will match yours. then raise you. High energy, intense mental needs, and deeply bonded to family. They thrive with active owners who hike, swim, or do dog sports.
