They keep sending a 3XL. I keep requesting a 2XL. I’m guessing they may be out of 2XL? My Frenchie is 11 months old, neck 17”, chest 23”,back 13” long…. It’s a bit big….However, the rain coat is gorgeous… good quality with vibrant colors. Please send me a 2XL and I’ll submit new pictures to help others with sizing for their fur baby.Great company to buy from, sizing is off. Order two sizes up,first one was way to small but they sent a replacement at no charge.Instant communication and sent another recommended due to exceptional customer service.( originally we ordered a medium for our jackrussellterrier/chichaua mix, but apparently we needed a XL)Love it. Not a huge fan of the front Velcro, comes undone easily but makes for easy dressing. Had to wait 2 months due to shipping issues but it was worth the wait.Thin jacket. Just a wind breaker type jacket. Cute though!I absolutely love, love, LOVE these jackets!! I started off ordering 4 of them. The Red Flag, the Blue Mountain, the yellow and the Black S in the larger size because I truly wasn't sure of her size because the charts on dog apparel aren't always accurate. That plus my dog is a Staffy so they have shorter but wider body frames. She also has been on a lower calorie diet and new exercise regimen so I knew at that moment she was right in the middle of 2 sizes. That lumped with the info that it would take a while to ship another size if needed, I got impatient when I saw that 2 of them were in stock as Prime items and would be here in 2 days! So, naturally I ordered 2 of the jackets in the smaller size. They do fit but were slightly snug. I was surprised how well it fit her Staffy frame. Being that the larger size were already on their way to us I decided on keeping all of them because in a couple of months she will definitely need the smaller size but until then I have the larger size for now! The size chart for these jackets is 100% accurate! They are not heavy winter coats but they are a fleece lined windbreaker! So they will keep your dog warm on chilly days but not for snowy days! They are easy to wash and easy to take with you as a "just in case" jacket. The seller is fantastic, easy to reach and eager to help! You can't go wrong with these jackets!! A great find!!Update: She now fits the smaller size so I ordered them in every color available! I love, love, LOVE these!!!I have a malinois/shepherd mix , he is HUGE 120 lbs , tall , lengthy and solid. I needed something for the rain since his fur is long , he comes inside all wet n muddy ! I also didn’t want something super heavy cause he’s got a thick coat already . I ended up getting the biggest size and it fits perfect ! The jacket is waterproof , it’s thin but really durable , it’s perfect for him , I highly recommend .Cappottino bello e di ottima fattura. Fornitore disponibilissimo, il pacco si era perso e me ne ha mandato subito un altro in sostituzione. Taglia perfetta.
