Rope is made of durable material
It is extremely sturdy and durable; Even if my dog pulls hard, it won't break. My dog is absolutely irresistible and gets excited every time he plays. Its design is very convenient for both of us, whether indoors or outdoors, it can effectively help my dog consume excess energy.

A Must for your Pup!!!
Pattern Name: Heartbeat Sheep White, Pattern Name: Heartbeat Sheep White
I adopted my puppy at six weeks and it was so hard for her to transition from leaving her mom and litter mates to my home. She would be whining and crying most of the time. I tried the water bottle with an old shirt of mine method which seemed to work, and I got on amazon in search for a plush that could soothe her. I came across this product, and I chose this one over the brand name because I thought the sheep was very cute lol. I recommend this product 100%! My pup loves to sleep with it and I immediately noticed a difference as she was soothed to sleep with this plushie. With or without the heartbeat, she loves to sleep with it regardless! I would love if this product, if the insert at the bottom could have more space as I would like to insert a heat pack to keep her warm. Also, my pup ripped out the nose stitches so just be careful with your pups as they may swallow the stitching! Overall, I love this product and I recommend getting your hands on one of these before your pup comes into your home. It’ll make the transition from mom to home much smoother.

Best investment to ease the transition for a new puppy!
Pattern Name: Heartbeat Sheep Grey
This toy is well made, the heartbeat sound that it makes is strong, and my puppy has loved it from day one! I just got a new Chihuahua mix puppy and the transition into our house was made so much better by all of us (the puppy, me and my other dogs) getting a good nights sleep each night because of this toy. My puppy snuggles with it in her crate and falls asleep very quickly. I'm sure it helps her feel like she is not alone and is very soothing. This is hands down the best thing I bought when planning for my new pup!

Helpful Idea for Puppies, Even Though Mine Were Not Interested
Pattern Name: Heartbeat Sheep Grey
This heartbeat puppy toy is a really thoughtful concept for helping puppies feel comforted during crate training and sleep, especially for very young puppies adjusting to a new environment. The heartbeat feature and soft plush design are clearly meant to create a calming effect and ease anxiety during transitions. The toy itself feels soft and well made, and I can absolutely see why many puppies respond well to it. In our case, my puppies personally were not very interested in it, but I honestly feel that was more about their individual personalities than the product itself. Because the concept is so good and many dogs may benefit from it, I still think it is worth trying, especially if introduced very early during puppy training and adjustment periods.

Did they add pheremones to this??
Pattern Name: Heartbeat Sheep Grey
So when my puppy first came home to me I bought this to try to help him keep calm through the night. He wasn't able to sleep through the night, but he did sleep more than I had expected. The next couple of nights he was able to sleep through the night completely (but liked to wake up at 5 am...). Fast forward to a month later, and I no longer turn the heart on all the time (because I forget). But I did buy a re-chargeable heart because having to keep buying batteries is a pet peeve for me. He still loves to sleep with it as it's another snuggle spot that helps keep him warm (short haired mini dachshund, so not much fur to keep himself warm) in the kennel. During the day though, he loves to drag this thing out of the kennel and "wrestle" with it. He shakes it a lot like all dogs like to do to "kill" it, and he's chewed the tail and nose worn. But the reason I say it has pheremones is that at 10 weeks old (which was younger than my last dogs' puberty age), he's humping it like there's no tomorrow. If I need to get his attention, or keep him out of a certain area, all I need to do is bring this out of kennel, and he's off humping the stuffing out of it. His brother (who belongs to my mother and is from the same litter), does the same thing. So now I have to wonder if they added some pheremones to it so that it's really "lovable". It was actually pretty hilarious because I was face-timing my mother showing her my dog with this anxiety toy, and he decided to perform his first humping act on air. So I'm not sure I can say it did it's main job to calm anxiety, but it did act as companion (in more ways than one) to my dog. My dog is almost 4 months old now and this toy is still going strong... well, the neck could use a sew, and the tail is on it's last leg, but he loves his girlfriend just the way she is.
