a dog will be very lucky to get 3hrs walking a day
I don't think there are many who walks their dog(s) 3 hours a day.
Everyone around me has dogs, we don't as I know how much work goes into them having grown up with dogs and I couldn't give them the time they need.
All the house aroud me leave their dogs out in the back garden, there are very few people who are SAHP, I see the cars going out from 6.30am and back after 7/8pm at night. As I am living beside them, I hear the dogs barking constantly.
The yoke woman beside me works Monday to friday, she has 3 dogs, 8 cats, they live in the garden and house, she actually leaves the back door open and lets them run in and out, she had her garden reduced in size due to building a shed the size of the Taj Mahal ! so very little room for them to run around, especially when you take into consideration the trampoline, table and chairs, built in planters, swing and slide set and the sand pit that takes over alot of the garden. She walks her dogs once a week on a Saturday for approx 1 hour. I have contacted the dog warden as I felt it was cruel but was swiftly informed that the pets are well cared for and once they have food and water left for them there is no amount of time that you are only allowed to leave a dog and once they have a small space to move around they are OK, this is Ireland so not sure if the same in UK. I do feel terrible sorry for the dogs but the dog wardens know best and they feel the dogs are happy.
Personally I feel if you get a pet that requires alot of walking, exercise and care you shouldn't get one. My parents when alive treated their dogs like humans, the legs would be walked off them, they were brought to dog parks, they brought them on days out, they went on holidays with them, so there are people who are fantastic with dogs and there are also some people who work and make sure their dog is checked on regularly, they may pop home from work or they don't work terribly ling hours.
I do think that some people need assessing before getting a dog, I know alot of people who should not be near any animal. BUt there are also some wonderful caring dog owners out there.
