Delilah Female Dog

LOST PawBoost ID: 72084248


Long Beach, CA 90831

On January 7th it will be five whole months since Delilah vanish. I still wake up every morning thinking about her trying hard not to cry and as I go about my day and go to all the places that I used to go to with her I usually fail at trying not to cry. I still check these lists every single day quite a few times a day actually and I usually cry at some point right before going to sleep her favorite time of day was going to sleep with me petting her and cuddling her. I was homeless when she went missing. Actually on the riverbed. Not where I wanted to be but it's just where I was at at the time my dogs never suffered not once. They ate better than I did they got to wake up outside every day near the beach near some water my dogs have always been spoiled rotten I've actually had friends say that when they die they want to come back is one of my dogs.... Delilah is my soul dog. The reason I became homeless is because I left an abusive relationship and Delilah used to catapult herself across the room and attach herself to my ex's face.. you should watch my every move she loved me just as much as I love her and I know she misses me just as much as I miss her. I would do anything to have my girl back. I used to tell people that when she dies they're going to have to lock me up cuz I'm going to want to go with her. But this? This is unfathomably worse. The not knowing wondering if she that day in August. Was it a coyote? I was always looking for signs of coyotes being nearby but I never saw any and I never heard of anybody seeing any near there. And I didn't see any signs of any kind of a struggle or anything and she would have put up a struggle she does not like other dogs. Wondering if maybe some evil person got hurt and they're just being mean to her somebody who doesn't treat their dogs right. Somebody who punishes their dog's cruelly or makes them stay outside when they have a that is indoors. My other two dogs are kind of starting to get back to normal. Chip Delilah's father was extremely depressed right after he's still very sad and he even cries almost every time he sees a dog that looks similar to her. Hank her half-brother still looks for her when we go places that I used to take her I can tell he's looking for her by his demeanor. All I know is what I thought would actually get easier (her still not being ) isn't getting easier at all.. it's actually getting worse and worse I'm missing her more and more everyday I'm crying more and more everyday I talked to her all the time and I just I got to have her if you know anybody who got a dog about 5 months ago that looks like her please try to send me a picture or contact me and I'll tell you a couple of things that would let you know if it's her or not I'm not trying to be mad at anybody if they I don't care how they got her I just need her back or at least I need to know that she's okay I need my baby girl back she's supposed to die a little old lady dog safe and comfortable as she can be like a decade from now in my arms knowing that she's loved if she's not supposed to just vanish and leave turmoil in her absence. Please help me find my baby girl I'm begging you please

Frequently Asked Questions

I lost my pet. What should I do?

Take advantage of online platforms – they help you get the word out, quickly and easily. You can report your lost pet to PawBoost in no time flat. We'll send an email alert to our local members, post to the PawBoost-powered Facebook page for your area, add your pet to our lost & found, and make a lost pet flyer – all for free.

Other sites that help you raise local awareness for your lost pet with minimal time and effort are Nextdoor.com – a PawBoost partner – and Craigslist. Both of these sites have very active lost & found sections mainly used for lost pets. We highly recommend you use these resources in addition to PawBoost!

Visit your local shelters and animal control agencies in person. Details can get lost in translation over the phone and that might lead to missed connection.

If chipped, make sure your pet's microchip is registered and up to date. If you don't know your pet's chip manufacturer or number, your vet should be able to help locate this information.

Put up flyers and tell your neighbors to be on the lookout. The more you engage the Costa Mesa community, the better your chances of a happy reunion!
