These were just a few of the poorly pets treated in one hour by what is now the UK’s biggest PDSA hospital.

Every week day, an average of 130 dogs and cats are seen by the staff of the Shamrock Street animal hospital. The consulting vets are scheduled to deal with a four-legged client every 7.5 minutes.

Some animals arrive limping or bandaged, others bloodied, but all benefit from free care offered since the centre opened in Garnethill in 1976.

The PetAid hospital – one of 43 in the UK – has just reopened its doors following a £290,000 refurbishment. Its four open-plan consultation areas of old have been transformed into seven individual rooms.

A state-of-the-art digital x-ray machine delivers clear images of broken bones or internal obstructions within seconds.

The reception area – a menagerie of pedigree pooches, pups in arms, and ailing moggies in pet carriers – has been expanded, with an intercom system calling through the next client over the tannoy. Its receptionists try to handle up to 60,000 calls a month.

The waiting area is a heady mix for the senses: occasional barking, growling and lively chatter fill the air.

Each of the adjacent seven consulting rooms have a PremVet computer system, where the medical history of each animal is recorded.

Vet Dermot Mullen said: “Ours is linked to Tollcross in the East End [the city’s other PDSA hospital on Muiryfauld Drive], so anything that comes in here, I can see every check-up it has had for the last six years. That means if I’m off next week then anyone else can see the same dog or cat and know what is happening with it.”

During the three-month refurbishment, the PDSA’s work transferred to the old Small Animal Hospital of Glasgow University’s Vet School near Bearsden, which in September unveiled its £15million new hospital.

The PDSA has been tending to the pets since 1942 when it first opened in nearby Woodside.

To qualify for free treatment, clients must be in receipt of either council tax or housing benefit, and live within a designated postcode.

Until recently, the charity, formerly known as the People’s Dispensary for Sick Animals, offered free treatment to only ill or injured animals.

Nowadays, eligible clients can also pay for preventative care such as vaccinations, worming or flea treatments, and neutering, at a subsidised price.

Deborah Low and eldest daughter Stephanie, 9, brought along their eight-week-old Border Collie, Pixie, for vaccination.

The 29-year-old mum-of-three from Cumbernauld said: “I’m not working, so you get help. I think it’s about £60 getting it elsewhere and about £28 here. ”

Elaine McGowan from Springburn brought in Jock, a West Highland Terrier she adopted from her uncle that caught kennel cough. She said: “I decided to take Jock on because my other dog died.”

Elaine and Jock left out a back door, for fear of the contagious disease being passed to other dogs in the waiting room.

Meanwhile, single mum and part-time student Claire MacKay had fears allayed that her adopted cat Ginger – who she found when she moved into a new house in Houston, Renfrewshire – had been knocked down or in a fight.

A mild bacterial infection was diagnosed. Ms MacKay, 29, said: “I don’t have unlimited funds, so for me it means she’ll not have to be put down for the sake of it.”

Just beyond the busy corridor serving the consulting areas lie the canine and feline recovery kennels. Some cages have red ‘Care’ stickers to alert the staff to dangerous or aggressive animals.

No such problem for pup Ace, who was found by his owner Martin Mather, 21, from Springburn abandoned in Ruchazie. Ace cowers in the corner, coming around from his anaesthetic to allow x-rays to be taken on his deformed limbs.

Cats sleep off their treatments in a new dedicated feline ward, that can house up to 14 moggies. The ward previously shared a space with the noisy laundry facilities, which are now next door.

The centre’s seven vets operate on a rota system. Lesley Low is in charge of the operating schedule today. She carried out two major operations in the morning – repairing a torn cruciate ligament and then a slipped kneecap (patella) – with more minor procedures such as dental work in the afternoon.

Three-year-old Rottweiler Levi is a model patient as his leg is shaved in preparation for a jab.

Once under anaesthetic, the vet cleans and stitches on the carpal pad that’s hanging off on Levi’s right forelimb, injured on a walk in Kelvingrove Park.

Owners James McGurn, 27 and Gillian Hughes, 26, from Partick couldn’t hide their gratitude as they pick up Levi an hour later.

Ms Hughes said: “We gave £10 today, but once we get back to work we’ll donate more money.”

On a noticeboard, a printed A4 sheet informs staff that last week clients made donations over the counter amounting to £4245.32.

Practice manager Martin Shevlin estimates that donations count towards around 25% of the £1.2million annual operating costs. Around half of PDSA income comes from wills and legacies, the remaining 25% from charitable donations and its chain of 177 charity shops.

Mr Shevlin said: “Veterinary bills are very expensive for those who are in low income, so therefore they wouldn’t be able to have that companion in their life.”

Lynda Leask, the part-time receptionist from Milngavie, will soon retire after working in Shamrock Street for 24 years. She said: “It’s like a casualty department at a hospital.

“All life is here.”
