Chloe is just under three pounds and loves to go on walks. I walk her and Sydney almost daily ...except in the winter... but I still try to walk them atleast twice a week on the better winter days. Sometimes we don't go far at all , just around the block or so , other days we do.. I have my sons or my dh with me most of the time , so I feel safe walking them. If I had to walk alone , I'm not sure I would do it as much and certainly not as far. I would also recommend a doggie sling or backpack type carrier for little ones. I will sometimes pick Chloe up and put her in a sling for a while to give her a break if we want to walk for longer than Chloe can handle.
I really hate them being dirty so I also wash their feet everytime we come in from our walks , it doesn't take much effort and I feel better about them walking on my sofa
I have never taken them to a dog park I just wouldn't feel comfortable there.
