Dog trainer issues advice to owners about ‘silent killer’

A dog trainer has issued important advice about a “silent killer” she believes numerous pet owners remain unaware of.

Sarah Rose, whose training school is in Cornwall, highlighted the issue in an informative TikTok video. She noted it happens far more often during the warmer months, so it’s advisable to pay attention.

The expert said: “I’ve not spoken about this before, and I have never heard other dog trainers talk about it either. So we need to make sure every owner has an understanding about it because I’m sure it’s something we all think we know, but we just don’t think about.”

So what is the hazard in question? She clarified: “Sand impaction. I’ve always known about this living most of my life close to the beach, but I have never known a dog become ill with it – until the last half term [May 2026) when two dogs here on their holidays got very poorly.”

Sarah added: “Make no bones about it – sand impaction can kill your dog.”

According to the trainer, there are two pastimes that dogs particularly relish on the beach that owners should remain vigilant about.

“That’s to play ball and to dig holes,” she detailed. “And both are very good reasons your dog might suffer sand impaction.”

Sarah’s guidance during the first pursuit is to “throw away all your tennis balls” and opt instead for smooth balls that sand cannot cling to in the “fuzzy bits”.

Furthermore, always guarantee your canine companion takes regular breaks from playing.

She added: “Within those breaks you should ensure you wash your ball in a rockpool or from any water you may have with you.

“Don’t keep giving them a sandy ball and make sure they drink from a bowl where there’s no risk of sandy water because clean water can actually flush any sand away as it goes into the mouth.”

When it comes to digging holes, Sarah witnesses this behaviour frequently.

While it can be harmless, it could have devastating consequences if dogs swallow a load of sand when their owners aren’t paying attention.

The trainer cautioned: “Unfortunately, this is probably one of the most dangerous ways to get sand ingested because they kick it into the back of their throats

“So please, if your dog is a digger on the beach, make sure that you stop them from doing this.

“Change their behaviour and shape a new one, or if they’re not willing to do that, put them on a lead and have them sit with you and chill out and have a break while providing fresh water.”

Sand impaction is dangerous because swallowed sand can build up in a dog’s stomach or intestines and behave like a physical blockage.

Common warning signs include:

• Repeated vomiting, not keeping water down
• Off food, lethargy, abdominal pain/bloating
• Diarrhoea or straining; stool may contain sand/grit
• Little/no poo (or persistent unproductive straining)

A partial blockage can progress to a full obstruction, and, in the worst cases, can compromise blood flow to the bowel. Sarah added: “This is what can kill your dog.”

If you have any concerns about your pet’s health, seek the advice of a vet as soon as possible.
