The dogs can get it off and they are short for a long snouted dog.  It rubs the german shepards nose.

We have had these for almost a year now, and they are very durable and work pretty well for our two small dogs. The only problem- the height of the actual individual steps is enough to discourage our small dogs (7 lbs, 22 lbs) from going BOTH ways on the stairs. The smaller one will only use them to go down, not up, and the larger one will gladly go up, but refuses to use them to go down. Perhaps our dogs are just nutjobs (entirely possible), but I feel like this would be less of an issue if the steps weren't so high. Ah, well, we won half the battle allowing the dogs to come on and off the bed as they please (since one must still be lifted up, and the other down).

Bought 3 of the medium ones for my 60+ pound dogs. For some reason, the latch has come off a few times when removing the clip from the collar. Might just be my big fingers trying to operate the latch. It takes some time to get the latch back on but can be fixed. The latch has not come off while the dog has been wearing the clip. If I order them again, I would get the large size.

it isn't so much that it is small, it is to short.

Works well; easy to put on and take off and generally stays put.
However, it's a little short. Actual length is 23". If your dog is around 27", like mine is, it still works. If your dog is longer than 27" from base of the neck to base of the tail, this coat will not cover the hindquarters.

Love how bright it is but the dogs can slip out of it and the Velcro adjustment is a bad idea

I have three Boston Terriers and they get tangled in this.  The shorter one would be better.  Would work with larger dogs. but not good for mid size or smaller dogs.

This product seems to work but size and quantitys are for smaller dogs.

The zippers keep separating and pets are able to burrow under the floor and get out between the spots that velcro.

I have tried this with my two dogs. My five year old does really well with it and has learned quickly how to walk with it. The puppy is pretty out of control and she spends her entire walk trying to get it off her snout. The quality is good and I certainly see how it can work. I just don't think this is the answer for my puppy right now.

Now that it is colder - it is a challenge to keep our two tiny chihuahuas warm enough in the house. We bought this so they could be snuggly with each other and have a safe space away from our two teenager large breed puppies. I wish it were a little taller - but it works for it's intended purpose. It is kinda tight for both my very tiny dogs - so I don't think anything larger than maybe a 15 pound dog would fit in there (and a cat or 2). We did let it air out for a few days before bringing it in the house and allowing the dogs to sleep in it. They enjoy it and will hang out in there on their own. I left the top off for the first few days so they could get use to the idea - and now it's closed and they love it.

Our dog got out of it pretty quickly with little effort.  The quality seemed ok, but it was never really put to the test.

I love that these last so long and the price is affordable. The con for us is our dogs are able to get them off too easily.

Maybe it's my dogs because they are small, min-pins, but they can't figure out how to get the treats out. I bought the small one and it's still pretty big.

We had high hopes for this one, but our dog (cane corso aka italian mastiff) was able to get out of these with no problem.  For smaller dogs who are maybe less persistent they might be of use.

It's had a bit of a short but for the most part for the price it is great.  I don't lose my dog at night anymore.

I got a small size for my 18lb doggie.  She cannot successfully pick it up and carry it, forcing her to bat it in order to get the treats out.  It did take a few minutes of initial training to show her how to use it (hint: use the PAW command), but she loves it now and starts batting her paws as soon as she sees it.
