FAQs About 2 Liter Bottle Bowls
Q: How often should I change the water?

Q: Can puppies use these bowls?
A: Only under supervision – ensure they don’t chew the plastic.
Q: What’s the safest way to cut the bottle?
A: Use scissors rather than knives, then sand edges thoroughly.
When to Avoid DIY Bottle Bowls
❌ For dogs that chew aggressively
