She knows a thing or two about different breeds (Picture: Getty Images/iStockphoto)

A vet has revealed the five dog breeds she would never own and her list includes some of our favourites.

Dealing with dogs day in and day out means @cat_the_vet knows a thing or two about breeds and their various behaviours, both good and bad. And now she is sharing this knowledge with others.

‘I’m a vet – and here I five dog breeds I would not personally own,’ she told her 325,000 followers.

‘Just hear me out, OK.’

German Shepherd

First on Cat’s list was a German Shepherd.

‘Absolutely beautiful dogs, but they’re bred to be suspicious and anxious which makes them really reactive dogs,’ she explained.

‘If they have a bad experience, they never forget it. They’re beautiful, but they’re big, they’re powerful and they can be really, really challenging – so just not for me.’

Flat-faced breeds

Flat-faced breeds include pugs, bull dogs and boxers and Cat says they would not be the dog of choice for her.

‘Next up is any of our flat-faced breeds,’ she said. ‘Again, absolutely fabulous little dogs but they do not deserve to suffer as much as they do.

‘And I could just absolutely never contribute to that suffering by deliberately owning one.’

Border Collie

Her next choice may come as a surprise, but Cat would personally not like to be the owner of a working border collie.

Why? Well, it seems many of the dogs have mental health problems.

‘Number three is the working border collie,’ she said. ‘I see quite a lot of these in practice bought from farms and kept as pets.

‘Huge numbers of them have mental health problems – these are dogs who need a job.

‘I just do not have enough time in my life to put into them to make sure they’re living their best lives with me.’

Shar Pei

Number four on the list is the Shar Pei breed.

‘Just generally a breed that doesn’t appeal to me personally,’ she added. ‘But also again lots of health problems and lots of behavioural issues as well.

‘Because of their health, they’re in pain and discomfort – and that makes them grumpy.’

St.Bernard

Finally, Cat admitted she could not own a St. Bernard or any large dog with jowls.

‘Quite honestly, I cannot cope with the slobber,’ she said. ‘I had a client once tell me that she had slobber on her ceilings.

‘I am 5’2″, I would need a step ladder to reach it. Quite frankly, there is more than enough to clean without me having to worry about the ceilings as well.

‘Really lovely dogs, very sweet – but honestly, I am just not good enough a housewife to keep up with these guys.’
