My family has a golden retriever named Dou Dou. It is smart, gentle, very friendly to people, and extremely affectionate. To be honest, this personality made me feel very at ease at first. On the day I brought it home, I thought that as long as I gave it enough love, it would become a “perfect dog.” But reality turned out to be much more complicated than I imagined.
Although Golden Retrievers have a good temperament, they are naturally full of energy. Once outdoors, it can barely control itself—it chases balls and jumps into water. One time, I didn’t have it on a leash, and it dashed across the street, nearly causing an accident. Since then, I’ve started seriously considering whether I should get Dou Dou a more functional collar.
The “positive traits” of Golden Retrievers can also be the source of trouble.
Doudou is smart but also mischievous; he loves me but will bark anxiously when I’m not around; he runs fast but doesn’t listen when I tell him to “stop”; he’s friendly to everyone, which can sometimes scare people unfamiliar with dogs. To put it simply, it’s not that the dog is bad—it’s that I haven’t set clear behavioral boundaries for him.
So, I started looking for a 2-in-1 wireless dog fence & dog training collar that could both train and manage my dog’s activity range. After comparing different options and trying them out, I finally chose the MimofPet X3pro portable training collar—it has completely changed the way I interact with my dog, Dou Dou.
Why do I strongly recommend the MimofPet X3pro portable collar?

This collar is not just an accessory to wear, but more like an “invisible teacher” and “invisible fence” for your dog. It combines multiple practical functions and is very suitable for medium to large, lively dog breeds such as Golden Retrievers:
1. Training + Invisible Fence in One: I can set up a safe activity area. Once Doudou approaches the boundary, the collar will emit a gentle reminder to stop, preventing it from getting lost or running onto the road.
2. Supports Simultaneous Management of Up to 4 Dogs: Our neighbors also have dogs, and we occasionally walk them together. The X3pro can control multiple dogs using a single transmitter, making it convenient and efficient.
3. 14 adjustable fence levels: Whether in the backyard or camping outdoors, I can flexibly adjust Doudou’s activity range.
4. IPX7 waterproof design: Doudou loves water, and this collar’s waterproof performance really gives me peace of mind—no worries about damage after swimming.
5. Lightweight and portable design: This is my favorite feature. No need to bury wires or connect to a power source—just carry it with you, and the fence can be set up wherever you go!
Comparison table of different types of collars
| Collar Type | Usage Scenario | Function Description |
| MimofPet X3pro (Electronic Training Collar) | Home/Outdoor Use | Invisible Fence + Training in One, Supports Multi-Dog Management |
| Leather Classic Collar | Daily Wear | Stylish and Comfortable, but No Smart Features |
| Personalized Nameplate Collar | Urban Walking or Backup Use | an Engrave Name and Phone Number for Easy Retrieval |
| Control-Type Leash Collar | Initial Walking Training | Prevents pulling and controls direction |
While other collars have their own uses, only the MimofPet X3pro truly achieves “all-scenario management,” offering both freedom and boundaries, so I no longer constantly worry about Dou Dou running off.
How has a collar changed my relationship with my dog?
In the past, I always felt like I had to chase after Dou Dou and bark orders at him, but now I don’t have to. Thanks to the gentle reminders from the X3pro, he can judge for himself what he can and cannot do. He has become more stable, and I am more relaxed. Especially when I’m not at home, he no longer gets anxious or crosses boundaries, which is such a relief!
Our communication is more effective, Dou Dou trusts me more, and I can finally work and travel with peace of mind.
Summary
If you’re like me and have a smart but overly mischievous Golden Retriever, if you want it to run freely yet follow the rules, and if you want “dog training” to become a mutual understanding rather than a source of stress—then I sincerely recommend you try the MimofPet X3pro collar.
It’s not just a tech product; it’s more like a “translator” between me and my dog. Since then, Dou Dou has become more attuned to me, and I’m more willing to take it on more adventures!
