I would rather guess from what I can deduce about Bella that since she was a only dog for a couple years..her behavior is typical for those dogs who never had to share before. I don't believe you can totally blame the breeder for this problem and I would guess that it will work itself out once the puppy becomes an adult. Continue to work on socialization while preventing any actually physical aggression. I believe a majority of all dogs behavior problems are environmental...occasionally a thyroid deficiency can cause aggressive behavior and with Bella being so tiny, it would be one thing to have the Vet check. Supplementation is inexpensive and can work miracles on behavior problems ( still it takes 3 months of meds to see any change) However this is a good case in point not to buy a puppy without some sort of a certified pedigree... You have no idea what is behind a dog without one..and sadly even with one..pedigrees can hold secrets. With perseverance..I believe you can overcome this problem Jenifer Jewell In a message dated 2/13/2008 11:08:41 A.M. Eastern Standard Time, [email protected] writes:
errors in causing her to become unbalanced. We have a new chihuahua puppy and Bella has nipped her. Bella is acting jealous over toys and food and treats. our new pup is 6 weeks old and is also a female. I suspect our Bella was from a puppy mill as we purchased her from a pet store. We recently heard about a puppy mill where interbreeding is causing smaller and more agressive chihuahuas to be put on the market. **************The year's hottest artists on the red carpet at the Grammy Awards.
