Dog Training/Older Chihuahua chasing younger Chihuahua


I have 2 year old Chihuahua and recently got a 1 month old longcoat chihuahua. When I first introduced the puppy to the older one at home, I figured that the older didn't know how to respond to the new born (She was drooling excessively). We just let them be. But the usual case is that the older would get annoyed at a younger pup because of it's playfulness right? But in our case, the older Chihuahua keeps on following the younger one who's just quiet and sleeps a lot. I don't really understand what the older one wants and I'd appreciate it if you could help me decipher her actions.

*both are female Chihuahuas. The older is not used to interacting with other dogs and gets used to other people if she constantly sees them.

The older dog may be trying to figure out what the younger dog is doing there and to maintain some control of the situation. It is difficult to say without out seeing them interact.

Patience, commitment and consistency are the keys to introducing a new puppy to your current dog. Here are some tips to help make the new arrangement a happy one.

What to Do When You Bring a New Puppy Home

1. Go to a neutral location, like a park, and walk the dogs on leash from the park back to the house.
2. Remove all the toys, bones, and other favorite items of the older dog so there is no possessive fighting potential. Then slowly reintroduce the toys after some time.
3. Pup will need to learn the rules of your household. The older dog should be able to teach the younger dog what is acceptable, just make sure there are any fights or attempted attacks. If things get too rough, make a loud noise or use a forceful voice to stop a fight. If this fails, put a chair or other large object in between the dogs. Never use your hands to separate your dogs at their heads, this is a good way to have one accidentally bite you.
4. Be sure to give your dogs plenty of one-on-one attention, and do it when they aren't near each other. You'll also want to create a neutral space, I use crates for that, for each dog, so they can retreat there as needed. Give food, bones and treats in this space only.
5. Praise any positive interactions -- this is the time to use your happy voice.

Watch for signs of aggressive behavior, and continue to provide positive reinforcement. It may take a while, but you can be successful introducing a new puppy to your dog as long as you're patient.
