Maybe you're wondering between long or short (smooth) coat. Yes, they both are very cute, I agree, but which one is a better choice for you? While long-coat Chihuahuas shed less, they also pick up more grass, dirt and debris from outside. The extra fur on their body is like a magnet for all of that, especially when is wet. However, this can be minimize by brushing their coat before letting them back inside. Because that smooth coat chihuahuas shed more you need to be prepared grooming them more often, but usually that's less time consuming. The choice between long and smooth coat is yours and there isn't wrong choice as long as you give them love and care.
The short answer is yes, but if is introduced at a young age. Bare in mind that most of the time they are in charge an could lead the rest of the pets.
That's a difficult one as chihuahua is a smallest breed with biggest personality. They are not aggressive in general, but living with small children could be a challenge. If you have kids of age under five is not recommended, but having a baby when you already have chihuahua is fine as long as you keep safe measure.
Hot. As chihuahua probably originate from Mexico cold weather is not something that they like.
Is not recommended to bath your chihuahua more than ones per month.
No, 15 - 30 minutes a day is enough. However, if you go on long walk and need to take them with you they can manage an hour or two, but take your chihuahua bag with you just in case.
No. Actually yes, you can see merle chihuahuas around more often, but they're are not pure breed. It's a mix with other breeds and this colour is not aloud from The Kennel Club in the UK, nor from American Kennel Club.
No, No and No!
Although, the term "tea cup" exists, there isn't anything like that in chihuahua world. There are breed standards and "the size as described does not imply that a dog will match the measurements given (height or weight). A dog might be larger or smaller than the size measurements stated in the breed standard"
