Pet owners are being urged to stay vigilant after mysterious stickers have appeared outside homes with dogs.
The small stickers have been cropping up across Merseyside with many fearing it's a way for thieves to target homes with family pets.
A number of social media groups including Wirral animal Samaritan’s have been sharing their own warnings and urging dog owners to stay alert.
One worried dog owner, who claims to have he found a blue sticker attached to her door, said: "Woke up to this on my door this morning.
"Never had anything like it before. I've obviously posted on the Crimewatch group only for head up to pet owners and to see if anyone has had similar.
"I've had a few sarcastic comments but as I've said I'm not usually one for all this but just find it a bit odd."
The dog owner says the small blue sticker was 'freshly stuck' and believes the colour indicates she has male dogs.
She added: "Both my dogs are male, one being worth a lot of money. Just wanted to let people know here in case is something to be concerned about."
The woman has now installed CCTV cameras outside her property as a precautionary measure.
However, she is not the only one who has found a sticker outside their homes in recent days, as others have reported similar happenings in the Birkenhead area in particular.
She said: "I really just wanted to let people know before it's too late. It's disgusting how we have to live.
"Luckily I have a dog who wouldn't let anyone q foot near the door but who's saying he wouldn't get poisoned or something?
"I know it's far fetched but it happens and for what my new pups worth, it's easy for them. This pup is worth more than everything in my home."
