I just found this dog in Huntington near home depot. No info on the collar.
FYI Dog will NOT be put down! They hold them for a certain number of days but that’s an expensive tracking collar — the owner is certainly going to come for them! If it starts blinking red then they’ve activated lost dog mode. It might be dead if you can put it on a charger. I’d bring to west hills

Do you have a dog walker?
Dog walker here: if an owner wants to meet me at the park (or even ride along!) they are more than welcome to do so Air tags or Fi Collars are welcomed and encouraged. Some dogs unfortunately sometimes get spooked or wonder off (they are animals after all) and having their location is a godsend in t

I was at work and my dog got loose. Has anyone seen her? Please help
Luis at Kilo K-9 is an absolutely amazing trainer. My dog was also an escape artist :) I would recommend getting a FI Collar or an AirTag as well!

Sitter did not notify owner that dog escaped
Reason #9,723,777,521 EVERY dog should own a Fi collar. I know its hindsight, but the owner would hv been able to see exactly when the dog escaped, could hv made the sitter aware that they know and most importantly would hv known within 50ft of where the dog was. Please get your dogs tracker collars

Running Away
Even better, get a Fi collar. AirTags require the dog to be near someone with an iPhone, Fi is satellite real time tracking. It’s obviously more expensive but if your girl is a problem runner it sounds like you need it.

Has your poodle ever run away from home?
We have a Fi collar and it has worked well thus far, as far as peace of mind. It stays charged for weeks, uses GPS or cellular networks to track all the time, and alerts us if our pupper leaves the yard. The company also works with a few other dog collar companies so their device can be put on diffe

Rover sitter lost my dog
I read your post last night, and honestly it kept me up all night. What an absolute nightmare you are having to go through. I’m not in Washington, so there’s not much I can do, but I just want to send positive thoughts and that I am not a religious person but I am praying to who ever that he is foun

How often do you dream about losing your dog or that someone stole your dog ?
I don’t have dreams like this, but this is one of my awake fears lol. Both of my dogs have Fi collars for a little bit of peace of mind.

Is it unethical to hire a dog walker?
No of course not. I run a pet care business and this is within my scope. Oftentimes, reactive dogs do better with me than they do with their parents. It is BECAUSE of that lack of emotional connection, they sometimes feel less anxiety because they aren’t acting out of protecting me. Sometimes people
