These dogs have got the character of a dog ten times their size, and can be feisty, and rule the roost.
You need to ensure that the dog will know its place within the hierarchy of the family.
Of all the aggression problems I get asked about, the majority are with small dogs... and quite a proporion of those are Chihuahuas.
neurotic"? What do you mean by this, exactly?
Already, I'm a little concerned for you....
I'm a Dog behaviourist.
Like Cesar Millan?
I'm here, and I'm free, aren't I??
I have recently counselled a home with four dogs: One Labrador, one Pit Bull terrier, one St Bernard, and a Chihuahua. Guess who was the leader?
Everybody thinks that because they're small, and cute, they'll be easy to handle.
Don't be fooled.
They're ferocious when roused, are perfectly able - and willing - to inflict a nasty bite when they choose to, and have a very dominant attitude.
This doesn't admittedly, always show up as aggression.
At times, it's just constant jumping around, noise, and attention-seeking.
There are very good reasons for this.
And excellent remedies.
You don't say how long you've had her, but it takes dogs about a week or two to settle into their new environment, before their temperament settles down.
If you have any questions or problems, feel free to ask, or PM me. Don't hesitate.
If you would like some help, with anything, I'll need to know how many members in your family, how many children, and ages, and whether you have any other pets, specifically dogs. What kind of environment you live in is sometimes a factor... Town, city? Apartment? Big house, big garden? That kind of thing....
Better to get things sorted now, than to have to seek remedies later.
