If a dog in my area is being left out in the cold with some days with no water what can be done

I would suggest acting quickly-esp w/severe weather coming up!! If u can safely take in animal immediately that would be nice IF u know amimal will respond gently to u + IF there's no owner around to challenge U'r actions. Keep in mind it can be risky to challenge an ownrr ALONE. Contacting LA SPCA on Mardi Gras Boulevard. OR Jeff SPCA in Elmwood area, close to Clearview + Erhart Blvd. might be helpful-- as they could likely advise u as well on how to connect w/ Animal Control or HUMANE SOCIETY to help remove animal + get it to safety .Even police dept. might be helpful in speaking w/owner or proper agency to protect animal. I know if u bring animal to N.O./LA SPCA they might attempt to reach owner. Otherwise u are asked if u wish to release animal into their care/they take over ownership of animal per se. Please don't give up if they don't answer calls right away.SO many calls come in 24/7. U mite need to go out there for help.

Take him in and then find his owner
