LOST PawBoost ID: 72410281


Denver, CO 80216

Black, white , tan with tan eyebrows her ears are black and floppy one is solid black and the other is black with white splashed on there, med build about 55 pounds. She will roll over if u approach her and wants her belly rubbed. She likes to be petted she will go to your hand and knudge it so u make sure you pat her beautiful head. She does not really like other animals except the ones she's grown up with...she especially has a issue with the small ones. She is, however, a sweetheart and I love and miss her so much. If you see her or have seen her around in someone's yard or walking please contact me please. I have a feeling that she is in the Swansea area perhaps on 47th where it ends and in a hse to the left. Not even certain of the street name. Please contact me asap if she's spotted!!! Thank you so much

Frequently Asked Questions

I lost my dog. What should I do?

Take advantage of online platforms – they help you get the word out, quickly and easily. You can report your lost dog 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 dog to our lost & found, and make a lost dog flyer – all for free.

Other sites that help you raise local awareness for your lost dog 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 dog'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 Boulder community, the better your chances of a happy reunion!
