I spent two hundred and forty seven dollars at the pet store the day before I brought my chihuahua home. Half of it went back within a week. The dog bed was too big. The collar was useless because she slipped out of it in under three seconds. The food bowl could have doubled as a swimming pool for a dog that weighs less than a bag of sugar. Nobody told me that buying chihuahua puppy accessories is a completely different game than shopping for a regular dog, and I had to figure it out the expensive way.
If you are about to bring a chihuahua puppy home, here is what I wish someone had told me before I handed my credit card to the cashier at the pet store.
Skip the Collar and Get a Harness Instead
This is the single most important thing I learned and I learned it almost too late. Chihuahuas have incredibly fragile tracheas. A collar puts all the pressure right on that tiny windpipe, and one excited lunge at a squirrel or a sudden pull on the leash can cause a collapsed trachea. That is exactly as scary as it sounds and the treatment is not cheap either.
A step in harness distributes the force across their chest instead of their neck. My girl barely notices hers now. She walks into it like she is stepping into a pair of shoes every morning. Look for one with soft padding and adjustable straps because chihuahuas come in wildly different sizes. A five pound chihuahua and an eight pound chihuahua need completely different fits, so do not just grab the first small one you see on the shelf.
If you are planning on leash training your chihuahua, starting with the right harness makes everything so much easier from day one.
Food and Water Bowls Need to Be Actually Tiny
Most dog bowls at the store are designed for dogs that actually weigh something. A chihuahua eating from a standard bowl looks like a toddler trying to eat cereal from a mixing bowl. Their little faces cannot reach the food without practically climbing inside.

You want shallow, wide bowls. Stainless steel is ideal because it is easy to clean and impossible to chew through. Weighted bottoms help too because chihuahuas have a genuine talent for flipping things over and then staring at you like it was entirely your fault that the water is all over the floor now.
One bowl for food and one for water is all you need. Keep the water bowl full at all times. Chihuahuas are prone to low blood sugar episodes and dehydration makes everything worse. I keep a second water bowl in the bedroom because mine drinks water at two in the morning like she just ran a marathon in her sleep.
The Right Bed Changes Their Entire Personality
Chihuahuas are burrowers. It is genuinely in their DNA. They do not want a flat open bed where they feel exposed to the world. They want something they can crawl inside of and disappear from everything.
A hooded or cave style bed is worth every single penny. My chihuahua disappears into hers like a little groundhog. She drags her favorite blanket in there, arranges it exactly how she wants it, and does not come out until she smells breakfast being made in the kitchen. If you disturb her before she is ready, you get the look. Every chihuahua owner knows the look.
Size matters more than you think. The bed should be snug, not cramped but snug. Chihuahuas feel genuinely safe in small spaces and a bed that is too big completely defeats the purpose. If you are crate training at the same time, the bed should fit inside the crate with just a little room to spare around it.
Grooming Gear Is Simpler Than You Think
One of the best things about chihuahuas is that they are genuinely low maintenance compared to most breeds. But low maintenance does not mean zero maintenance and I learned that lesson the hard way too.

A soft bristle brush is the first thing you need. Short haired chihuahuas shed more than you would ever expect from something that small. A quick brush twice a week keeps the tumbleweeds of fur under control around the house.
A dog toothbrush and dog toothpaste are completely non negotiable. Chihuahuas have the worst dental problems of almost any breed on the planet. The American Kennel Club lists dental disease as one of the top health concerns for the breed. Their tiny mouths crowd their teeth together and plaque builds up incredibly fast. Start brushing early and make it a daily habit before they decide they hate it.
Nail clippers or a grinder are essential because small dogs have small nails but they grow fast. If you can hear clicking on the floor when they walk, the nails are already too long. And a gentle formula dog shampoo for baths about once a month is plenty unless they roll in something regrettable, which they absolutely will at some point.
If you have a long haired chihuahua, add a detangling comb to the list. That is honestly about it for grooming.
Toys Need to Actually Fit in Their Mouth
Most dog toys at the store are built for dogs that can actually fit them in their mouths. A standard tennis ball is basically a basketball to a chihuahua. Rawhide bones designed for medium breeds are a genuine choking hazard for a dog this small.
Chihuahuas want small, soft toys they can carry around and shake like they have caught something incredibly dangerous. Mine has a stuffed squirrel that is almost as big as she is. She has had it for two years and still takes it to bed with her every single night. I tried to wash it once and she sat outside the laundry room and cried until it came back.
Rubber chew toys designed specifically for small breeds work well for teething puppies. Squeaky toys are always a massive hit with chihuahuas. Fair warning though, you will hear that squeak in your dreams and it will haunt your quiet evenings forever.
The Things Nobody Puts on the Standard List
There are a few items that are never on any official puppy checklist but completely saved my sanity during the first few months.
Puppy pee pads are essential even if you plan to potty train outdoors. Chihuahuas hate rain. They hate cold weather. They hate wet grass. They will look at you with complete betrayal in their eyes if you expect them to go outside when the weather is anything less than perfect. Pee pads are your backup plan and you will use them more than you expect.
A small blanket is both a comfort item and a genuine necessity. Chihuahuas get cold constantly. They shake when they are cold, when they are excited, when they are nervous, and sometimes just because they feel like it. A blanket they can burrow under makes everything better for them.
Stain and odor spray. You will absolutely need it. This is not a reflection on your training skills, it is just the reality of living with a puppy whose bladder is the size of a walnut.
A car seat or small carrier is something people forget about until the first vet visit. Chihuahuas should never ride loose in a car. They are too small and too fragile for that. A secured carrier or dog car seat keeps them safe during the drive. If you are planning to fly with your chihuahua eventually, the right carrier does double duty for both car rides and flights.
What You Can Completely Skip
Dog houses are pointless for chihuahuas. They should never live outside, period. They simply cannot regulate their body temperature well enough for outdoor living in any climate.
Fancy outfits are fun to look at in the store but unless it is a sweater for genuine warmth during cold months, save your money. Your chihuahua does not care about fashion. She cares about being warm and being near you and that is honestly the whole list.
Automatic feeders sound convenient but chihuahuas eat so little that portion control matters more than automation. You need to actually see how much she is eating every day because changes in appetite are one of the first signs that something is wrong with a chihuahua.
The truth is that chihuahuas do not need much at all. A safe place to sleep. Something to eat from that fits their tiny face. Something to chew on. And you. Mostly just you.
My girl could not care less about the forty dollar orthopedic bed I bought her on that first shopping trip. She sleeps on my pillow every single night and always has. But that eight dollar harness I grabbed from the clearance bin? She will not leave the house without it.
