💡 Quick Tip

Do two dogs cost double? Not exactly. Learn about "economies of scale" in pets, what is shared, and what multiplies exponentially when expanding your animal family.

Buying decisions are rarely rational. Modern marketing uses cognitive biases to push us toward immediate consumption. Understanding how your brain works is the first step to shielding your economy.

📊 Practical Example

One dog costs $80/mo. You think two will be $160. But with two, you need a bigger car or pay extra pet-fees at hotels. The marginal cost of the second pet is often higher due to logistics.
