We had originally ordered a 5XL, which was too big, we returned it for a 4LG and it’s great!! She looks beautiful, the leash and a carabiner hook her in safely and she doesn’t tip over when we brake anymore!! I feel much safer and I feel like she’s much safer, without her being a 120lb projectile in my car anymore. I thought I’d email and let you guys know everything is wonderful, from customer service to shipping, to returns and the actual products.... great!!!! I can’t get my husband to get our lab one fast enough!!
