Dogs for Good says many owners are worried about going back to work and parting with their pooches again.
Dogs for Good - based in Banbury - has issued guidance to dog owners to prevent 'separation anxiety' as lockdown eases.
It comes after a recent survey conducted by the charity reveals that over half of dog owners in the UK are worried their pet will be anxious when they return to work.
More than half respondents (53.2%) say they haven't started to reintroduce their dog back into a normal routine, such as leaving them at home for a short period of time to minimise their anxiety when lockdown ends.
Over half (54.8%) have also been walking their dog more during lockdown.
Dogs for Good provides highly trained assistance dogs to people physical disabilities and families who have children with autism. The charity also supports people with learning disabilities and dementia to help them lead more independent life with the help of a trained dog.
The charity's Operations Manager, Chris Muldoon, said: "You've been in lockdown, perhaps even isolating, for over two months and as a result, you've been way more interactive with your dog than ever before.
"Thus, some will get confused and upset by the fact that they're not going to have as much time with you as they've recently enjoyed.
"Dogs are social animals and they thrive on routine. Six weeks ago, the rules for them changed dramatically and what they don't know is that it's all going to change again.
"Fortunately, because we'll likely see a phased return to work, school runs, socialising etc. we really do have time to help our dogs and build their ability to cope."
He added: "You could start by picking up your keys/bag/coat etc. saying your usual 'goodbye' to your dog and then leaving the house for a short amount of time - five or ten minutes.
"You can then build this up gradually over two to three days to an absence of half an hour and continue from there."
Hannah Beal, Dogs for Good Family Dog instructor, said: "Dogs will not only have to get used to people not being around as much, they may also have to cope with added stress in the house.
"If the children aren't coping well this obviously has an impact on the dog.
"People are worried about getting back into a routine and we have to pre-empt that there may be problems and put preparations in place before they come up.
"For example, many of our clients have already been practising leaving their dog alone, making sure they aren't visible by going upstairs, and gradually building up the length of time they are away."
Dogs for Good top tips include:
- Bring back the old routine gradually.
- Start talking to your colleagues/managers about how to manage your dog responsibilities when you return to work, for example ask if it would be ok to check on your dog regularly in the first few weeks/months of returning.
- Take a note of your dog's behaviour and think about how this may change when you're out of the house and away from them.
- Your dog might bark more when you're not at home to reassure them as much, consider letting your postman know you're going back to work and your dog may bark at them.
- Reintroduce old routines, such as not leaving food on counters, to prevent scavenging when you are out.
- Re-install baby gates that may have been taken away during lockdown and make sure doors are closed when you go out.
