One vet has revealed the five dog breeds he would never own including a family-favourite.
Now, if you own any of these dog breeds, then don't worry - they are still very good girls and boys.
And, like with purchasing any animal, it's paramount that you do a huge amount of research to make sure they align perfectly with you and your lifestyle.

According to TikTok-famous vet, Amir Anwary, there are a few reasons as why he's not too keen on owning these five dog breeds.
Border Collies
Amir explained the first breed up on the rundown was none other than Border Collies.

"Now I love Border Collies guys," he assured, "but these dogs are bred to be working dogs they need to be physically and mentally stimulated every single day."
The vet also revealed that 'most people that get a border collie don't understand this', adding: "This breed is designed for herding sheep on a farm so it's extremely difficult to keep them happy in a city setting."
And, on top of all of this, Border Collies are also 'prone to hip dysplasia and arthritis'.
He added in the comments that if you are able to 'provide them with regular exercise and stimulation' then you can 'defos own one'.

Cavalier King Charles Spaniels
Next up is the Cavalier King Charles Spaniel, which Amir admits is 'probably one of the nicest breeds I've ever worked with'.
However, he warned that these adorable little pooches suffer from a genetic health condition called mitral valve disease which causes Cavalier King Charles Spaniels to go into congestive heart failure at 'a young age'.

The vet continued: "Often dogs are affected as soon as seven years old, but this can be delayed up until 10 years old, at which stage most cavities will be affected.
"And what does that mean for you? It basically means your dog may die at a young age or, best case scenario, they will be on medication for their heart for the rest of their lives."
Any brachycephalic dog breed
What on earth is a brachycephalic dog breed?

Well, brachycephalic simply means shortened head - so this encompasses any dog out there with short snouts and flat faces, like pugs, English and French bulldogs.
Amir explained: "Now I love these dogs guys, but because of their squish faces, they suffer from a condition called brachycephalic obstructive airway syndrome."
The animal-lover says that this condition comes about due to all the 'anatomical abnormalities with the squished face' meaning that such pups 'struggle to breathe' as well as 'struggle with temperature regulation and exercise intolerance'.
"This exercise intolerance often leads them to picking up weight, which makes temperature regulation, and which makes breathing, even more difficult." he adds.
"So it's a very bad self perpetuating cycle with these dogs."
Dobermans
Second from last on the list are Dobermans as they are prone to a heart condition called dilated cardiomyopathy.
Amir describes the condition as when the heart muscles become thinner and the heart chambers become larger which, in turn, makes it 'very difficult' for the heart to pump blood throughout the body.
"So because of this, they're going to require regular checkups, and they may also need to be on lifelong treatment for their heart," he added.
Great Danes
And last on the South African vet's list of dog breed he would never own are Great Danes.
Though ironically, he does in fact own one - or half of one.
He told viewers: "Guys, I love Great Danes.
"I have a Great Danes cross but the purebred Great Danes can only live for about seven to eight years, which in my opinion is so little and for that reason, I would not want to own a purebred Great Danes."
