What people think “dog freeze” means
The internet is full of confusing stories and sensational headlines about pets being frozen after death. Unfortunately, this often leads to misunderstandings about what’s actually possible — and ethical — when it comes to preserving a beloved animal companion.
For some, the phrase “dog freeze” evokes:
- Home freezer preservation
- Freeze-drying taxidermy
- Sci-fi scenarios of suspended animation
What is pet cryopreservation?
Pet cryopreservation is a process that preserves your pet at extremely low temperatures, aiming to maintain cellular and neurological structure in a stable, long-term state.
Unlike freezing, which forms damaging ice crystals, cryopreservation uses:
- Cryoprotectants (a type of antifreeze) to replace bodily fluids
- Vitrification, which turns tissue into a glass-like state without ice formation
- Liquid nitrogen storage at –196°C
This process is used in cryobiology around the world — from preserving embryos to storing organs — and has now been adapted for end-of-life pet preservation.
The steps of pet cryopreservation
When your pet passes away (or is close to passing), we will arrange all necessary custom and logistics. Our specialized transportation partner will arrange to collect your pet and bring them safely to our facility in Rafz, Switzerland. Upon arrival, your pet will be preserved using your chosen method, either Standard or Advanced Preservation, and stored securely in a dedicated cryogenic dewar. Your pet will remain safely preserved indefinitely until future medical technology may allow for revival.
Is this the same as freeze-drying or taxidermy?
No. Freeze-drying is a form of preservation for display — often used for pets but unrelated to the goal of revival. Taxidermy, meanwhile, preserves external appearance, not internal biology.
Cryopreservation aims to preserve identity and brain structure, with the idea that if future science advances far enough, restoration may be possible.
It’s not about memorialization. It’s about potential continuity.
Why people choose cryopreservation for pets
Losing a pet is a devastating experience. Some owners take comfort in memorials, cremation, or burial. Others — especially those already interested in human cryonics — see cryopreservation as a way to keep the option of future reunion alive.
Reasons people choose pet cryonics include:
- A desire to avoid irreversible decay
- A scientific worldview that values preservation
- The hope that revival technologies may one day extend to animals
- A sense of peace in knowing they did everything possible for their companion
While there are no guarantees, cryopreservation provides a bridge to future possibility.
How much does it cost?
Pet cryopreservation is far more affordable than human cryonics. The cost depends on your pet’s species and size, but services start around a few thousand euros.

Where are pets stored?
Preserved pets are housed in the same state-of-the-art cryonics facilities as human patients, in specialized dewars. Tomorrow.bio partners with the European Biostasis Foundation (EBF) in Switzerland, offering:
- Secure, long-term liquid nitrogen storage
- Temperature stability at –196°C
- Facilities designed for decades or even centuries of safe preservation
- Separate dewars for pets of different sizes
This isn’t about “freezing your dog” — it’s about entrusting them to a process grounded in scientific care.
Are there ethical concerns?
Any new approach to end-of-life care can raise important questions. But pet cryopreservation is based on the same principles as veterinary medicine and human cryonics:
- Informed consent from the owner
- No suffering (only performed after legal death)
- Respect for animal dignity
- No false promises about revival
Cryonics does not claim to bring pets back today. It simply preserves the possibility.
Understanding the term “dog freeze”
The phrase “dog freeze” has become a kind of shorthand — but it’s misleading. No pet is frozen like a popsicle. Instead, pet cryopreservation is:
- Structured
- Ethical
- Backed by biology and technology
- A way to extend hope into the future
Let’s stop imagining deep freezers and start talking about real, responsible preservation.
