Tasmania's reptile catchers have reported a surge in activity, with panicked home owners finding snakes anywhere from under beds to inside cars.

In the past few weeks, statewide snake catching service Reptile Rescue has received about 40 to 50 calls a day.

"It's unusual activity, the [snake] activity has been quite prevalent, and it's not even anywhere near peak time," snake catcher Justin Kneebone said.

"We've had our first warm spell and snakes are definitely out and about looking for food, water and mates."

Three pet dogs died during the week after being bitten by snakes in suburban backyards in Hobart.

Lara Crawford lost her Staffordshire terrier Clyde and her great dane Jersey on Wednesday after they were bitten by a snake at their Risdon Vale home.

Ms Crawford said she brought the dogs inside for their evening feed when her partner noticed Clyde was completely paralysed.

Then they noticed Jersey's back legs had gone and she was trembling.

The dogs were taken straight to the vet.

"There was nothing they could do for Clyde, they had to put Clyde down," Ms Crawford said.

Ms Crawford also had to make the heartbreaking decision to euthanase her great dane.

"You can't have a great dane on wheels, not being able to use their back legs, so we had no choice but to let her go."

A Maltese terrier also died this week after being bitten by a tiger snake at Lutana.

'In cars, under beds, in shoes'

Mr Kneebone said Tranmere, Acton, Cambridge and Lenah Valley were among the hotspots in Hobart and surrounds.

"We're building in areas that used to be bushland so these snakes don't know any different, so they're just going about their normal business and going through yards that used to be bush trails," Mr Kneebone said.

Reptile Rescue catchers had found snakes in all sorts of "weird and wonderful places" including inside cars, under beds, in shoes and even in a lunch box.

"I've been out on jobs at two or three o'clock in the morning where people have come home from a night out and there's a tiger snake near the garage or at their front door," Mr Kneebone said.

"People's first reaction is usually panic. The first thing we try and do is to tell them to calm down, [if it's inside] try and secure the room, shut the door and put a towel across there. That will limit our search area."

"If it's outside, keep an eye on the snake from a safe distance, we often get calls where we get there and they say 'it was over there 20 minutes ago'.

"Snakes move very fast so if people keep an eye on it, it narrows down our search area so we can remove [the snake] and relocate it.''

Snakebite signs 'tremors, shaking, difficulty walking'

Tasmanian Animal Hospital Vet Dr Andrew Dudgeon said dogs were naturally curious when it came to snakes.

"The problem is dogs love to play with snakes and so if a snake were to enter into their yard then they would want to go and investigate it, they would want to smell it and attack that snake," Dr Dudgeon said.

"A snake has no interest in biting dogs, it's only a survival mechanism.

People are being advised to be mindful of where they exercise their dogs.

"Beaches are great for dogs at this time of year, bushland is not," Dr Dudgeon said.

He said snakes were attracted to houses or built-up areas because they were looking for water.
