Aww so adorable! So well knit!
This is exactly what I've been researching lately, patterns for chihuahua-size doggie sweaters for my 14 yr old chihuahua 'grandson' "Pedro"! He belongs to my DS and his family! Pedro is older than the grandchildren! He is always so cold except for summer. They've put a heating pad in his dog crate, on low. The kids are excited about Pedro having some warm sweaters. I have some angora-wool blend stash yarn set aside for him! Not machine washable, true, but I think warmer than acrylic. He needs animal fiber!
My DIL is holding Pedro!
