They may be tiny, but anyone who's ever owned a Chihuahua will tell you that these little pooches can in fact be quite a handful.
However, don't let this put you off as with the right care and attention this breed can make great pets that will often happily live with children and other dogs.
However, as Sarah Linehan of The Pet Experience points out, it is important to ensure that you are aware of the level of care that these canines require before taking the plunge and bringing your four-legged friend home.
"Chihuahuas should be cared for just like any other breed," she says. "They need good quality food, good daily exercise - a minimum of one and a half hours every day, good mental stimulation for their active brains and plenty of security and stability."
It is also important to make sure that you are feeding your Chihuahua the right diet according to their lifestyle and breed, as under or overfeeding these little canines could result in serious health problems.
Dry dog food is often the best option for any pup but it is worth speaking to your vet to ensure that your four-legged friend is getting all the nutrients they need and that they are munching down the right quantity for their size.
With a tiny pooch it can be tempting to spoil your pet with treats but Sarah Warns that Chihuahuas are "very clever and very strong-willed" and that they can be "yappy and snappy if not raised correctly".
Therefore, it is important that you raise your dog with training and discipline from day one so that they don't slip into any bad habits that could result in behavioural problems later in life.
Many owners fall into the trap of carrying tiny dogs everywhere and feeding them food from the dinner table, but this could spell trouble in the future, so resist the temptation to over-indulge your pup and you will find yourself with a happier, healthier dog.
