They are sturdy, there is a band that goes behind his head and underneath his ears. The straps is adjustable and underneath his chin. The glasses had like a soft rubber, I’m guessing to prevent the glasses from moving around. But because the shape of the glasses it kinda slid down Mickey snout. But for the price not bad.My Dog looks kool in them ?I got these for my blue eyed huskey since they have a predisposition to getting eye issues and because he's always squinting I figured you probably wouldn't like wearing them on his face but that overtime he would like having them so that then he when the train's eyes so much but when they arrived they were clear. Similar to safety glasses with a slight tint. I ordered white and I didn't see much of a difference until after they came and I took a look and realized the white I saw was the background not the tint of the shades I'm not sure why the worst grabbed is white because only white thing about them or when they run his head you can see is the white further through the clear plastic LOL. Disappointed they couldn't have done a better job describing these because now I gotta return em and not even bother trying the other pair. Just hope someone else sees this before they have to go through the hassle of going to the ups storeLooked adorable on my blind dog and helps keep the bushes from scratching his eyes.I tried with my blue tick and my pit. Neither one fit right. It dug into their noses on the sideUn poco grandes para mi perro pero en general muy bnTucker is an average sized, 15yo male Shiba Inu and these fit perfectly! They are made well, sturdy and with a great adjustable fit. I was impressed with the design and how they stay secure on the dogs head as comfortably as possible.He has serious cataracts in both eyes, so I bought these to help him outside. Unfortunately, he will not wear them; instead, he walks around the corner where I can't see him and shakes them off his head LOLPersonally I find these to be a great product, made well, priced right and suggest them to anyone.Razón de compra: Mi perrita tiene dermatitis atópica bajo tratamiento, algo en el ambiente ocasiona que sus ojos enrojezcan y le da comezón. Para evitar que (lo que sea que la esté afectando) aumente y no salir a pasear con el collar isabelino decidimos utilizar doogles.Producto: Material resistente, en ningún momento se le safó el elástico. Aunque mi perrita se sacudía. No lo coloqué ajustado para no incomodar y noté que se sostienen bien sin tener que apretar.Sugerencia: mi perrita es tipo Beagle, la medida del tamaño de su cabeza es perfecta; sin embargo, para su hocico no queda muy bien, para su tipo de cara serían mejor unos en los que la curva sea más ancha y permita que se ajusten a su cara en la totalidad y no queden tan despegados.You get what you pay for. My dog is blind, main purpose it eye protection. I measured according to measurement given on Amazon, should of been a near perfect fit. Not even close, makes him look like his head is deformed. Lenses repeatedly fogged up due to being ill fitting. They worked for the intended purpose, with numerous stops in our walk to adjust glasses back over his eyes. Fogging didn't much matter as he is blind. Nose area is definately smaller then advertised.These goggles are not for dogs, unless your dog has the face of a human. You get what you pay for I guess.. The bridge area of the goggles did not fit flush for our 5 month old lab pup. It may fit ok on smaller dogs but buyer beware.I didn't have a chance to return it bc my pup ripped it to shreds. Ended up ordering some rex specs instead and very happy with those.These were for my dog who is going blind. They looked like they were going to work great. I liked that they were clear and not sunglasses since I didn’t want to take away any remaining vision. Unfortunately, they sat to close to her eyes and sometimes touched her eyeballs. They also fogged up right away, possibly due to the proximity to her eyes. Sadly, will have to return.Was excited about these...but disappointed as I quickly realized these are HUMAN goggles w straps. Which means the divet for the nose would fit a cartoon whippet... if it skipped a few meals .Our long faced husky looked cute in them and they kind of worked but wind would catch in the nose part and make them move.Cute for a photo but not practical
