Fitwarm Sweet Donut Dog Pajamas, Cute Dog Clothes for Small Dogs Girl, Pet Onesie Cat Clothing, 100% Breathable Cotton, Pink, Small

My dog has a 25" chest and a 21" length, I wish Fitwarm made larger sizes. He may not be a toy dog but he's always cold (even in August in SoCal!).

My dachshund has a 22 inch chest and 18" back. What size should i order?

What size would I buy for my 20 inch long 18 lb. cat?

I have a 140 pound dog what size could I buy her?
