Not So Great with a Maltese, but good for bigger dogs!

Small faces don't work as well with this product.  I have used the Gentle Leader before on a Lab and a Brittany Spaniel and they were wonderful.  I ordered this for my Maltese and it hasn't worked out at all.  I feel like I have experience with training on the Gentle Leader so I suggest you stick to using this with larger breeds and you should be happy.

Ok, so at first we really liked the product, it seemed sturdy enough. However after a couple of months it seems to be weakening and my 60 pound senior dog keeps slipping off of it. This is supposed to help dogs climb up to higher places they can't jump up to, but if you have a senior or a dog with back and hip problems, you may be better off with a ramp. The steps are rather narrow for our lab. It also tends to wobble when she climbs up the steps. Our other lab that is only 4 years old just jumps right over the steps altogether. It's perfect for a Maltese sized dog.

Great for little dogs too! I looked around for dog perch but only saw ones for cats, so I picked this up and sure enough, it worked! It holds my 13 pound Maltese poodle mix just fine but wished it was maybe 2-3 inch wider in diameter. The tricky part is trying to make a step rail to get her up. I used a gym flat bench, some textbooks, and stacked ottoman seats so she can get up easily.

I have a maltese mix, it works pretty well to help remove small matted areas. You just gotta be gentle and patience.  I just needed something to help maintain her coat with her regular brushing and dettangler spray.  It does the job and seems pretty durable, I've had it for a few months now.

Bought these for my Maltese and he loves to run and chase after them. He's 5 months old and only 4 pounds, so they are a little big for his mouth. If you have a smaller dog, I'd suggest something else.

We tote our Newfoundland around in this and it works well. Our Newfie is about 100 pounds right now and we have to have the top open so she fits, but it works. Not sure if it will still work for us when she weighs about 130, but I'm hopeful. I wish they made a trailer that was just a little larger than this, but AFAIK, this is the biggest one unless you spend a lot more money. Would buy again.

I have a maltese mix who is just under 10 pounds and has a 14-15" chest. I ordered this harness to use in the car. In case of an accident I don't want her in a normal harness. I imagine this will give a little extra comfort in the rare occassion that we are in an accident and the car flips or she is knocked off the seat. I use this in conjuction with a seat belt clip. Ideally, I'd like the harness to be a little more snug but the small was just to small so the medium it is. Maybe Puppia will add an in between size because the difference between the small and medium is quite a lot. Overall I really like the harness and feel it is best for car safety and comfort!

My maltese is 13 pounds. The medium is a little baggy on him, but it fits and is super cute. The belly portion hangs a little bit so sometimes he'll get a little urine on it, lol. Other than that, he likes to physically pick it up and bring it to me to put on :)

I love this, my maltese loves it also! It is sturdy and lightweight. The only thing I would add is a handle on the back because I transfer it back and forth from house to cabin.

Works perfect with smaller dogs but if you plan on working with larger dogs or even with difficult small dogs I'd get the thicker one. If the dog pulls too hard or struggles too much the clasp comes undone. Almost got me bit!

My dog likes this carrier. He is a 12 lb Maltese. He sits in it with his paws on the front lip. He can almost lay down in it, but it is tight. He likes to stand in it most of the time. It sits high enough so he can see out the front and side windows. The top strap just goes over the back of the seat. However, the lower strap must be threaded around the lower portion of the seat and connected behind the seat. This makes it a little bit cumbersome if you want to take the unit out and use it elsewhere on a routine basis.

Sadly, it doesn't seem to stay still. Both my dogs got their legs stuck because it was loose enough that their legs pulled out and over the harness while walking. They weren't even struggling, just walking. It's possible I need an extra small, so I'll try to get it exchanged. But overall, I don't know if I like this product for my dogs size.
However, it may work fine for bigger dogs with more chest to hold the harness in place!

THE DESIGN: I have a taller bike, and so I had a bit of trouble installing this so that the leash would be low enough for my dog; then when I did get it at the right height, I had to angle it backwards so that my leg wouldn't constantly hit the pole as I pedaled. It perhaps isn't designed for all bikes.

MY DOG'S REACTION: My dog is part dalmatian, so she is a bit freaked out by new experiences. I had to roll into the biking thing really slowly, and after some failed attempts to attach her to it because it was too high, she seemed completely freaked out by the whole process. After that, I had to cajole her with lots of treats.

DOGS THAT PULL: she is a very large dog, and feels the need to lunge at ALL other dogs and cats. On our second trip I didn't notice a black lab in a neighbors front yard, so didn't detour. She definitely can pull the bike off course. My only recourse, given that I have her on a harness is to pedal really hard against her pulling. I don't think this is very safe. Perhaps this can work for even medium dogs that pull, but it felt a bit dangerous with her.

I am giving this three stars because it is fairly easy to take on and off (although not with dogs that reject the idea of being tethered to a suspicious wobbly device). It feels sturdy, and when I did get her going she got some exercise in. I'll keep trying. Perhaps it is best to start young (I rescued her at 5yo).

This is really a good product, but the trick is how to get your dog to try it.  I have two dogs -- a Cairn terrier and a spaniel.  They both resisted lying on the mats (large was good for my medium sized dogs).  The vinyl did not have a terrible smell like some have complained about (I did cleanse them with Lysol towels), so that wasn't the problem.  I put them in each of their favourite places to rest on the screened in porch, but they changed their places once finding them there!  Finally the spaniel lay on one half of one and, finding it cooler there, now is putting her whole body on it.  The Cairn terrier is still resisting, but I hope will follow the other's example.

These really are cool to the touch, and I think will make a big difference once both get accustomed to them.  I would recommend trying them.  If anyone has tips as to how to encourage dogs to use them, please add to your review!

My Maltese did not like the smell/taste.  When he did eat it, I didn't notice a difference.  Keep in mind that we didn't use it consistently as recommended.

The groomer clipper is a good thing with my little Maltese.  I did have one mistake in the order in that I got two #1 heads and no #1.5 head.  I will work around this mistake.

Dogs love it, but get really gasy. Anyone else notice that? Maltese has a weak tummy but other than the gas issue eats this well. I've tried Blue Buffalo as well and they seem to be comparable.
