The Horse is the first pet in Ride A Pet that actually blocks progression. It is not sold in the Shop and it is not a reward you claim from a menu, so the only route to it is hatching the right egg enough times. Until you own one, Rebirth 1 stays locked no matter how much cash you bank.
Quick answer: Collect and hatch Glass Eggs, which spawn near the stone tower and the cliff ledges around your plot. Horse sits at 1 in 500K, so plan on a long run of repeat hatches.
Horse hatch odds and what the pet unlocks
The Horse comes out of the Glass Egg, the transparent egg type that is easy to walk straight past. Its rate is listed in the pet Index at 1 in 500K, which makes it a volume grind rather than a lucky single pull. The same egg also holds the Fox, the pet you need for Rebirth 2, so the eggs you crack chasing a Horse are not wasted effort.

| Detail | Value |
|---|---|
| Egg source | Glass Egg |
| Hatch chance | 1 in 500K |
| Progression use | Rebirth 1 requirement |
| Cash needed alongside it | $1M |
| Other pet in the same egg | Fox (Rebirth 2 pet) |
Rebirth 1 needs both halves of that requirement at once, the Horse sitting in your ranch or inventory and $1M in cash. Completing it adds +1x to your money multiplier and +1 pet slot, and opens up alternate ranch skins.

Glass Eggs favour a fairly tight band of terrain rather than the whole map, which is what makes farming them practical. Keep your route inside the space between your base and the outer ring of rocks, and sweep it repeatedly instead of wandering.
- The stone tower and the ground immediately around it
- Cliff ledges on the elevated ground above the base
- The river perimeter and riverbank paths
- The gap between the base and the outer rock line

The Glass Egg is translucent, so it blends into rock and grass. Slow down on ledges and check silhouettes against the skyline rather than relying on colour.
How to farm and hatch Glass Eggs

Confirming the Horse and clearing Rebirth 1
You will know the hatch landed when the Horse appears as a new pet at your plot and fills its entry in the Index. From there you can mount it directly or place it in your ranch, and it stays valid for the Rebirth check either way.

Once you have the Horse and your cash reaches $1M, choose Rebirth on the left side of the screen and confirm. Before confirming, review the live panel to see what resets, because Rebirth removes your cash and any Luck purchased from the board inside your ranch.
Do not sell the Horse after Rebirth 1. The Rebirth chain checks a specific pet at every stage, and re-hatching a 1 in 500K pet later costs far more time than keeping it parked in a slot.
After that first Rebirth clears, the same Glass Egg loop keeps paying out, since the Fox needed for Rebirth 2 shares the egg. Keeping the tower and cliff circuit running while your multiplier climbs is the cleanest way to line up both pets without changing routes.
