Dog owners are sharing images online of the destruction their pooches left after destroying Kmart’s supposed ‘chew-resistant’ pet beds.

According to the retailer’s website, the $42 bed is made of ‘chew-resistant material’, however many naughty dogs have defied that claim and left theirs in tatters.

The buy has received mixed reviews online with many owners claiming their dogs have not been able to penetrate the tough material.

An animal behaviourist told FEMAIL owners should be ‘mindful’ of anything that claims to be chew-resistant and shared some tips to stop dogs from destroying their beds and other things around the house.

‘To SAVE you wasting your money, don’t buy this bed from Kmart for your pet. It is definitely NOT chew resistant,’ one woman wrote in a post to the Markdown Addicts Australia Facebook page.

She shared a photo of her dog asleep on top of the stuffing from the bed he had chewed through and spread all over her back garden.

Thousands were amused by the dog’s cheeky behaviour and said theirs had done the same thing with the Kmart bed.

‘Sorry for the laugh, funniest thing I’ve ever seen. Thanks for the heads up,’ one group member laughed.

‘Yep, didn’t even last one night. I actually took it back and got a refund,’ another said.

‘Yeah even my chihuahua was able to chew through it,’ a third added.

Some laughed the dog was still sleeping on the destroyed bed and looked like he was tired out from chewing it up.

‘Looks like he got his moneys worth,’ one woman joked and another said: ‘He looks exhausted, consider it enrichment’.

Others pointed out the bed was advertised chew ‘resistant’ not chew ‘proof’ which means it is designed to deter dogs from chewing rather than stop them completely.

‘I’m sure it put up a good fight (resistance). It did say resistant, not chew proof,’ someone

‘Resistant just means it’s harder not chew proof,’ another agreed.

But not everyone had a problem with the bed as many said theirs were still in tact.

‘My dog is a massive chewer and we have two of these and never had any issues but I have made sure the zip cannot be undone,’ one pet owner replied.

A customer wrote a review on Kmart’s website saying: ‘It works! I have an staffy-cross-mastiff puppy who explodes dog beds every week.’

‘I was just about to buy a $300 ‘chew proof’ bed that I was sure she’d destroy anyway when I saw Kmart had one. It has been one month! Not chewed and completely intact.’

The woman’s post prompted dozens of dog owners to share the messes their pets had made after chewing up cushioned beds that claimed to be resistant from Kmart and other retailers.

Dog behaviourist Lara Shannon said the ‘biggest reason’ dogs can be prone to chew up their beds or other items is out of boredom closely followed by anxiety.

‘It’s attention seeking behaviour as well and the fact that dogs are opportunists, they love to chew so if there’s something there, they’re going to chew it,’ she said.

‘Obviously the big thing is ensuring your dog has plenty of enrichment in their days both mentally and physically.’

The Melbourne animal trainer said to make sure your dog gets regular exercise and to leave them with other chew toys that provide mental stimulation.

‘Rather than leaving them with just their bed as company during the day as a potential chew toy, find other items that are more appropriate for them to relieve their anxiety,’ she said.

Lara recommended leaving dogs with chew toys or congs with frozen food inside to preoccupy them.

‘It takes them a while and tires them out. It makes them feel good and less likely to want to chew out other things of boredom,’ she said.

If your dog is anxious, Lara advised talking to a veterinarian or animal behaviourist to provide appropriate tools and solutions to make them feel more at ease.

She also said to avoid inadvertently playing chase or tug-of-war when trying to take back something your dog has gnawed through.

‘By turning it into a game, they’re getting your attention and the behaviour is being reinforced so it continues to happen over and over again.’

Lara warned owners to be ‘mindful’ of any pet product that says it is ‘chew resistant’ as it is a ‘game claim’.

If a dog is prone to chewing their beds, she recommended opting for ‘less enticing’ mesh beds on a steel frame that are available at most pet stores.
