I have two adorable apple-headed chihuahua puppies. Both are females, one with a short coat and the other with a lengthy coat. They are currently 5 weeks old and weigh less than a pound; when fully grown, they will weigh 3-4 pounds. They still don't have their ears totally up; if they did, they'd be a lot cuter!! They are not "Mini"; there is no such thing as a mini dog! As you can see, both of them have excellent circular shaped heads and are 100 percent pure bred apple heads. Both have wonderful personalities! They will get their vaccinations up to date. I can see both of my parents. Mom has a small coat, while Dad has a long coat.
