2 lost PitBulls have been at my house for a week (Aztec/RiverSide Park)

2 PitBull dogs have showed up at my house for the last week. I desperately need them to be claimed. I don't want to call animal control to destroy them. They don't get along with my dog, other wise they seem really sweet. They both have collars, no information is on them. I'll let anyone that wants them adopt them. They just really need a home. They were lost at RiverSide Park area
