There are physical and behavioral traits with this breed that are not necessarily considered 'negatives'; but only serve to give you a good understanding of what to expect.
1) Size
This is the smallest dog purebred dog breed that exists. Some photos of Chihuahuas may be misleading that do not relate the actual size of the dog.
Additionally, there are some Chi that are larger than the breed standard. However, in general, you can expect to have a very tiny pet.
Puppies range from mere ounces to 1 to 2 lbs. (.9 kg). Most adults will only be 6 (2.7 kg) to or 7 lbs. (3.17 kg). There are some that grow to be 8 or 9 lbs. (3.62 or 4.08 kg) however this is still small in comparison to many other breeds. There are advantageous and disadvantages to this:
Advantages:
- You can bring this dog with you to many places - Many owners find that even places that do not necessarily admit dogs will make exceptions for toy breed dogs that are carried in canine slings. Alternatively, placing a Chihuahua in a travel bag is an option that owners of large breed dogs do not have.
- This breed does not take up a lot of room - With some breeds, it is almost like having another person in the house. When you have a Chihuahua as a pet, he takes up very little room. In small apartments and homes, he will need daily exercise but will not need a huge yard or a large dog bed. Baths can be done in the kitchen sink. Adults can easily sleep in an owner's bed without taking it over.
- Smaller bodies equal smaller outputs - Quite frankly, with toy dogs, bowel movement and puddle of urine are small in comparison to larger breeds. When you have a Chihuahua as a pet, even if the dog has accidents in the house - no matter his age - clean-up is not often overwhelming. Do keep in mind however, that without proper house training and dealing with any marking issues, this will add up and will create quite a mess.
