Congratulations — you've been selected to serve. Whether your chihuahua just arrived or you're preparing for one, here's what actually matters in the first months of the reign.
1. Warmth Is Infrastructure, Not Luxury
Chihuahuas run cold — it's physiology, not preference. Set up a draft-free bed (they love covered or "cave" beds for burrowing), keep blankets in their favorite spots, and plan on a properly fitted sweater for anything under 60°F. If your new dog trembles, check temperature before assuming anxiety. Full details in our temperature guide.
2. Feed Small and Often
Tiny dogs have fast metabolisms and small fuel tanks. Most chihuahuas do best on 2–3 small meals a day rather than one large one; very small puppies need even more frequent feeding to avoid low blood sugar. Ask your vet for portion guidance — obesity is the other cliff, and it's a short fall for a 5-pound frame.
3. Socialize Early, Gently, and On Purpose
The chihuahua reputation for spice is mostly under-socialization plus a world that's genuinely enormous from six inches off the ground. Calm, positive exposure to people, sounds, and (carefully selected) larger dogs in the first months builds a confident adult. Let them approach; never force the greeting.
4. Guard Them Like the Small Dog They Are
Big-dog play, being underfoot, jumps off couches, and birds of prey (genuinely, in some regions) are real hazards. A harness — never a collar alone — protects the fragile trachea common in the breed. Teach kids the two-hands rule for holding.
5. Dental Care Is Non-Negotiable
Small breeds have crowded teeth and chihuahuas are dental-disease champions. Start tooth-brushing tolerance early, use vet-approved chews, and budget for cleanings. It's the single most neglected chihuahua health item.
6. Expect a Velcro Dog
Chihuahuas bond hard — usually to one primary person — and want to be on you, not near you. Build short, positive alone-time from day one so separation doesn't become distress. A worn t-shirt in their bed helps (they didn't choose the merch life; the merch life chose them).
7. Find a Small-Dog-Savvy Vet
Ask specifically about experience with toy breeds. Discuss dental schedules, patella (knee) checks, and weight tracking at the first visit.
