24/7 Pet Hospital Season 2 is yet to be announced by BBC One

Labrador Jasper is brought into the hospital by his owners after struggling to breathe when out for a walk. His tongue is swollen, and it's blocking his airway, so he is prioritised for immediate treatment. Bobby the spaniel has arrived with his owner to have tests to find out why he's suffering from ongoing symptoms, such as sneezing and shaking his head. They hope it's not cancer. Meanwhile, Skye the Bernese mountain dog is treated by orthopaedic surgeon Magic for joint problems, which can be common in large breeds.

Puppy Coal from the Dogs Trust is being treated for aspiration pneumonia, caused by food going into his lungs. He was born at the hospital on Boxing Day by caesarean section, so the team have developed a close bond with him. However, over the last six months, he has suffered repeated infections. After numerous admissions, the team decide to operate to give him the best chance of a normal life. Also in the pet hospital for an operation is Grayson, a border collie puppy who has broken his leg after falling off a bed. With the break near his growth plate, it's vital to get it right. In oncology, a new scanning technique is being used for the first time to check if Poppy the labradoodle has the all-clear from cancer.

A dalmatian puppy called Reg is rushed into the hospital after eating a mystery object that's become stuck in his intestines. A scan shows that there's only one way to get it out, and that's to operate. Rupert, a King Charles spaniel, has an appointment to see the experts in the neurology department to try to get to the bottom of his headaches, which can be common in this breed. Becky, his foster carer, would also like to find out what she can do to cure his life-threatening lung infections, and so clinical director Ben looks into his case. In the oncology department, the team are seeing Alexandria, a cat who is undergoing chemotherapy. They hope this will be her last chemo round and give her some well-deserved treats.

A Pomeranian puppy called Bear has had an accident and caught her leg in a conservatory door. She sees surgeon Laura, who fits a tiny metal plate to fix her broken bones. It's not always easy treating dogs as small as Bear, but the team adapt. Meanwhile, a cat named Esme is brought in by her owner Kirsty as she has stopped eating and is being sick. As Esme arrives in the consulting room, the team take one look at her and rush her into ICU as they're concerned about her breathing. Colin, a basset hound, arrives for his check-up, supported by his sister Dolly. He has been suffering bouts of pneumonia, so his owner Andrew hopes the medication has helped and he'll get the all-clear.

In this episode, we follow the night-shift team as they treat numerous emergencies, including a cockapoo called Milo, who has been brought in after being sick for an hour, and a six-year-old ferret named after a pop star, who is bloated and not his usual self. It's former veterinary intern Iason's first night in his new out-of-hours role, and he's got 40 furry patients to look after with the team. On his next night shift, a dog is rushed in by her owner after collapsing, and the emergencies continue into the next day, when a St Bernard cross called Wolfie breaks his leg on a walk. Rubble the greyhound is in to give blood, and his fifteenth donation means he's helped save the lives of around 60 other pets.

Black labrador Bilko is referred to the hospital as he's had an extreme allergic reaction. Despite treatment by his vet, he appears to be getting worse. Initially stable overnight, he takes a turn for the worse, and his heart rate means staff must monitor him closely. Attempts to anaesthetise Bilko for a scan cause further concern, and the team call in cardiologist Brian to treat him urgently.

In the consulting room, a Belgian malinois named Hope arrives with her owners after a huge mystery lump has appeared on her throat. Surgeon Anna investigates.

In the neurology department, they're also looking for answers. Roxy the dachshund is shaking so badly that she is unable to walk. The team come together for solutions.

A French bulldog called Appona is rushed in by her owner after struggling all night to give birth. She is carrying five puppies, but after doing an x-ray, the team are concerned that the puppies' size may cause complications for mum. Just as they're about to go into theatre to perform a caesarean section, a call comes through from ICU with a surprising development.

In neurology, rescue kitten Eric has intermittent lameness in his back legs, but further tests reveal that the problem may not be neurological.

In the orthopaedic department, surgeon Fran is seeing Marley, a six-month-old labrador puppy, for a six-week check-up to see if his operation to repair a cartilage defect has been a success.

The critical care team work to save the life of a tawny owl that has been found badly injured on the roadside and brought in by a passing motorist. He's cold and frightened, and his body is starting to shut down. Although the team are more used to treating animals with four legs, they pull out all the stops to try to save him.

Meanwhile, in one of the hospital's four operating theatres, orthopaedic surgeon Magic tackles a challenging hip replacement on a tiny six-year-old shih tzu called Alfie.

In reception, the client care team are looking for the owners of a lost dachshund puppy brought in by a local priest and his wife, who found the pup wandering the streets. With no details of the owners on the dog's microchip, they turn to social media for help.

Six-year-old Labrador Nugget is referred to the hospital by his local vet when they find a mass on his right kidney. He needs specialist tests. Walter, his 87-year-old owner, took on Nugget when his previous owner, Walter's daughter, died. Walter is worried that it could be cancer, and he may lose him too.

In the hydrotherapy department, they're dealing with one of their most challenging cases, Pepper, a French bulldog who is learning to walk again after surgery to fix her collapsed spine. Devoted owners Toni and Lucy are prepared to sacrifice everything to see Pepper back on her feet.

The pet hospital is also holding its first ever open day, but just as the first visitors are arriving, they have an emergency to deal with.

Series following the work of the specialist vets, staff and animals at a 24/7 pet hospital in County Durham.

The emergency team treat two boxer dogs who've been caught snacking on a fruit and veg box. They're worried about the indigestible corn on the cob. If the cob is too big to remove by an endoscopy, they need to resort to surgery. Older brother Hugo is given the all-clear and sent home when he comes round from the anaesthetic, but six-month-old puppy Casper has something stuck in his intestines that they can't get to. If it doesn't pass naturally during the night, the team anticipate surgery the next morning.

On the night shift, the hospital takes over the out-of-hours emergency service for 25 vet practices in the north east, and tonight veterinary intern Marina is called to deal with an unusual case - a cat struggling to give birth. Surgery is the last resort, so they try an alternative method.

On the dog ward, a popular patient is back. Guide dog Sherpa comes to see surgeon Anna for a check-up on his wounds. Having previously stayed at the pet hospital for a month, Sherpa has a close bond with the team, who are excited to see him again.
