Adopted a dog.

Got my daughter a dog as a early birthday present. He is a beagel mix. He is a wounderful dog but so far doesn't really get along with one of the others pets. Our cat don't like him. He trys to chase our bunny. We do have a trial week so if it don't work out we can give him back. Hoping he'll learn to leave the bun alone soon. Our cat use to being the only pet in our room so might change but well see. It's only been one full day. Hoping it works out cuz my daughter loves him. If it don't. Going to get a kitty instead then might be better.

Does anyone have tips that might help?
