A woman says her garden is plagued by snakes which are attacking her dogs.
Natalie Garrod says she wants to warn people that snakes aren't just a danger on beaches and in the wild and is urging people to be alert.
Vets had warned dog owners before the Easter weekend to keep a close eye on their pets because of snake bites.
And a large snake appeared in Cardiff's Roath Park on the weekend .
Natalie says her eight-month-old puppy narrowly avoided being bitten by an adder at home on Easter Saturday, North Wales Live reports .
She said: "We heard our French Bulldog puppy barking - but it was a noise and bark we'd never heard him make before. We ran out to check what was happening and we saw the snake ready to strike the little dog but luckily we managed to grab him just in time and get him away.
"Obviously the snake was trying to protect itself but it was still very frightening. We're having to keep the dogs on the decking - it's not very nice. It's a bit scary as we have to make sure all the doors are closed to the house during the summer to make sure none of the snakes get inside. This is the second snake we've had in the last three days."
But it's not the first time her dogs have been under threat - with her boxer being attacked three times in three years and her Boston terrier also bitten once.
"Each time we have to ring the vets and rush them there within 20 minutes to get them treated as the venom can spread so quickly. The dogs had to have injections to put their heart rates down and the boxer had to stay overnight once as it had been bitten two weeks apart one summer," she said.
The 41-year-old from Llanengan, near Abersoch , said that she and other family members regularly see snakes in the garden when the warm weather arrives.
She said: "It is awful sometimes. I think people know to look out for snakes in the wild and on the beach but they don't always think they could show up in their own back garden.
"The snakes are literally everywhere here. My neighbour says he sees them slithering from his house down to ours. We think that they are coming to our pond to get to the water - we're pretty sure there is a nest somewhere. I've probably seen about 40 snakes - sometimes it can be two or three a day in the summer. My Taid used to teach us not to lift the stones in the garden in case there were snakes nesting under them - so we know quite a lot about them luckily.
"About three years ago, I left my wellies outside and they fell on their side. I'm terrified of mice so I made sure to shake them to check if anything was inside and a little adder tipped out of them.
"We contacted the council over it a few years ago but there's not much they can do because they're a protected species. We were told that we cannot do anything to them or we could be prosecuted."
Adders are the only venomous snake native to the UK and are roughly around 2ft (50-60cm) long and have a black/brown zig-zag pattern along their back and V or X shaped markings on the back of the head, according to vets4pets.
The species is protected by the Wildlife and Countryside Act 1981 - this means that it is an offence to kill, harm, injure, sell or trade them.
