I have a 10 month old mixed puppy. I've done a lot of research of both of the breeds that she is mixed with and I still don't understand what her problem is. She is a Louisiana Catahoula Leopard Dog mixed with a Basset Hound. Very odd mix I know. She is super protective over me. She barks at every noise. She growls and barks at anyone who comes into my house ( even if she knows them). I take her to my parents and she barks at all of them and runs away with her tail between her legs. I take her to the dog park 4-5 days a week for almost 2 hours each time. She does great with other dogs, until two weeks ago when a dog started a fight with her at the dog park. Now she is picking fights with dogs. I don't understand where it is coming from? Her and my roommates dog rough house but that's it. I don't understand why she is acting like this and why she barks and growls at everyone. I've socialized her A LOT since I got her at 9 weeks old. I honestly don't know what to do with her anymore, shes is embarrassing to take out on walks and to the dog park because of the way she acts.She acts like she is a nervous mess 24/7. She has never showed aggression towards a human, but i'm afraid she will.
