My pup is very comfortable and secure in this harness. I use it on leash and attached to his car safety harness.El material está excelente y es muy cómodo y fresco, pero las medidas son grandes para el perro. A pesar de que está en sobrepeso le quedó grande.I’ve used this harness on a 12lb Yorkie for 6 months. I was worried that it might not be sturdy enough to withstand her Very strong pulling and jerking against it—but it is!!! It has stretched slightly, but not enough to be a problem. I’m very happy with it and will buy another in a different color.My beautiful pup is 13 weeks. 19 lbs. She is in a size small…but won’t be for long! Perfect for right now. Note - this harness has only a back loop - but does not keep her from pulling - it does protect her neck though!!!We like this type because our Boston Terriers need the harness to be adjustable at the neck and chest separately. This one does the trick.Nice but not durable enough for my dog. I'm afraid she'll be able to break the cords since she plays hard.I got a small, I could have gotten a xsmall. Champ is about 7lbs and is a yorkie bichon mix. Even when his fur is long there is still room for him to wiggle out if he is determined to do so.I really love this harness it's very durable very sturdy fits very good. It also is very cute.Möchte jetzt niemanden schockieren, aber wir haben dieses Hundegeschirr für unser Schwein gekauft. Da wir nur eins haben, gehen wir mit Ihm öfters spazieren. Passt gut und hat nach 6 Wochen keinerlei Schäden. Er wühlt sich sehr gerne im Dreck und man kann das Hundegeschirr super sauber machen dannach. Ich denke man kann sagen, wenns eine Sau aushält, kanns bei einem Hunde auch was aushalten.[Updated Review] 05/11/18I left a 5-star review about 2 weeks ago but have since had to update my review to remove 2-stars due to a major issue with the design and quality control.► The major issue is the sliding adjuster on the chest strap. If you adjust the chest strap for your dog and the sliding adjuster happens to be roughly on top of their body around their spine or 3-4cm either side, as the dog moves around while walking the small tab of material the D-Ring is attached to moves around from side to side as it's not fixed in place on the chest strap. This causes the D-Ring to catch on the sliding adjuster and slides it open! Yes, 3 times now in less than 10 walks one of my doggos has nearly got out the harness and run off because the adjuster has slid open meaning only the neck strap is holding them in. This is a major issue and something so easily resolved by the manufacturer.► The second issue is quality control: one of the harnesses I bought has stitching coming undone on the neck straps where the D-Ring connects to it. The funny thing is this is on the puppy harness that we've on used 3 or 4 times for 10-minutes in our garden just to get her used to having a harness on, so it's not from excessive use or catching on bushes while walking, it's barely been used but we now need to get a tailor/seamstress to pop a few strong stitches into it to repair it before we can use it outside._________________________________________________Pros:• Extremely bright/Hi-vis! No seriously, if you shine a torch at your dog you run the risk of blinding someone on the International Space Station.• *Feels strong enough for my doggos, although they're not strong pullers and they only weigh 4kg, 6kg and 9kg (Since experienced stitching coming undone on 1 of the 3 we bought)• Fits and adjusts nicely, very comfy and breathableCons:• As mentioned above - the D-ring can move around which catches on the adjustment slider, causing it to slide open allowing my dog to get out the harness!• As it states in the description, these are definitely made for puppy, small or medium dogs, not large or strong pulling dogs. Although they feel well made I would put a limit of 10-12kg for the L/XL version or less if the dog is a strong puller.Overall: I purchased 3 of these, Pink (S), Orange (M) and Yellow (L) - They're very comfy, bright, and good-looking, but since using a few more times over the weeks I'm no longer sure if I would recommend them or buy them again. Shame.Great harness for our Golden Retriever puppy (9-13 weeks). The smallest measurement fit him perfectly with some wriggle room for when he grew, and seemed to be comfortable for him too. We decided to go for a harness as he was constantly biting his lead when it was attached to his collar and this certainly deterred some of that behaviour and gave us more control when walking him. The harness is sturdy and stands up to pulling, although slightly fiddly to get onto an excited puppy early in the morning!We've just ordered another two, M and L, as he is now measuring up to a M at 14 weeks and will soon grow out of that too. I would definitely recommend these.Lovely lightweight harness, excellent value for money, took a little while to arrive but definitely worth waiting for. Have taken a picture so you get the general idea of what it looks like.I purchased the XS size of this harness for my tiny kitten. The harness fit okay on the smallest setting but was still little bigger than I was comfortable with. I put a couple of stitches on the neck part of the harness to make it a little tighter and it now fits perfectly. This was the smallest harness sold on Amazon that I was happy to put on my cat (I don't like the H style harness) The first photo is before I made the alterations and the second photo is afterwards. Overall very pleased, a well made and comfortable harness for my tiny cat.
