Top 14 dog breeds at risk of life-threatening conditions and high vet costs

Dogs have been bred to fulfil certain roles, whether it be as working animals or pets. While that breeding may have been helpful or amusing to humans, it has created a host of issues. In fact, one vet has claimed breeding has created a "psychopath" dog breed .

For example, many bulldog and French bulldog varieties are bred with disproportionately large heads to their small hips, often requiring the mothers to undergo a cesarean section to deliver. Even more concerning, some puppies might get stuck in the birth canal, putting the mother's life at risk .

The same danger applies to Mastiffs, who may need surgery for birth – an expensive and perilous operation.

Additionally, certain canines have been bred for wrinkly or "loose" skin, predisposing them to painful infections and inflammation; susceptible breeds include Shar Peis and Neapolitan Mastiffs. Infolding eyelids can also scratch and irritate the eye, causing discomfort and unnecessary suffering.

Certain breeds like the Hairless Chinese Crested dog face increased cancer risks because of their vulnerability to heat and sunburn, while the dense coat of Chow Chows sets them up for potential overheating complications, reports the Express .

Breeds with short, flat faces, such as Pugs and Pekingese, are subject to "severe breathing difficulties" heatstroke, and even fainting episodes, with some needing surgical intervention just to breathe adequately, noted the animal welfare charity: "Some dogs' nostrils and windpipes are so narrow they need surgery just so they can breathe properly."

Large hearted dogs bred to be very large, such as St Bernard and Dogue de Bordeaux, can suffer from hip dysplasia, lameness and arthritis. Similarly, the Dachshund, with its long body and short legs, is prone to "painful and debilitating spinal problems", much like the Corgis.

It's also noted that up to 70% of Cavaliers develop painful "syringomyelia, which is a hereditary brain condition common in toy dogs bred with skulls that are too small for their brains". Highlighting the risks of severe health problems and costly veterinary bills, the RSPCA commented: "We believe that all those who breed dogs - whether pedigree, purebred or crossbreed - should prioritise health, welfare and temperament over appearance. This will help protect the welfare of both the parents and puppies."
