Feeding habits and pet interaction

When it comes to interaction with other animals, our dogs are surely anti-social. They chase even the birds in the garden so when our dogs are in the front yard (we let them loose there for some time regularly) there are no birds around. But in fairness to our dogs, they are quite friendly with the lizards inside our house. They don't chase the lizards and just ignore them. There was a time when we had a pet pigeon inside the house and that winged pet blended with the dogs.
