The RSPCA has warned against dressing up pets for Halloween, saying it can be "quite stressful" for animals.

While some pets may not mind being dressed up, some may find the experience "worrying and even scary", the RSCPA told ´óÏó´«Ã½ Newsround.

The British Veterinary Association says certain dogs can feel discomfort or suffer breathing problems in a costume.

The warnings come at a particularly popular time for pet costumes, in the run-up to Halloween on Monday.

Many pet owners post social media images with their pets in fetching pumpkin or ghost costumes, while some owners have taken their dogs to Halloween costume parades, primarily seen in the US, but also increasingly in the UK.

But the RSPCA says pets do not always find such activities to be fun.

"It's really important that pet owners think about how dressing up pets can make them feel, as whilst some animals may not mind being dressed up, other pets may find this worrying and even scary," the animal charity said.

Justine Shotton, the vice president of the British Veterinary Association (BVA), added it can also affect some animals' health, in particular that of certain breeds of dogs.

"It can cause them to get stressed, get too hot and struggle to breathe properly," she told ´óÏó´«Ã½ Newsround.

"This can be a serious problem for dogs like pugs and French bulldogs, who can already have breathing problems because of their flat faces and squishy noses."

However, an organiser of a Halloween-themed pet parade that took place on Sunday stressed none of the animals appeared to dislike being in their costumes.

Deepika Sharma, who arranged the event in Wembley, north-west London, told ´óÏó´«Ã½ Radio 5 Live that the 35 to 40 dogs in attendance "absolutely loved the attention" and were "very happy".

The RSPCA says pet clothes that serve a practical purpose can be useful if it is cold or if the animal needs to be prevented from licking a wound.

And the BVA's Dr Shotton added that healthy pets "already have lovely coats which look great and keep them the perfect temperature" and so "they really don't need to be dressed up in costumes".
