Wow! I have the same problem! Angel is a couch potato! He really doesn't like to go for walks! When he was young, I carried him until we got to a side street with no traffic! He tolerated it. At the park, he walked and sniffed, behaved, pretty much, but again didn't really like it! I used treats to make it exciting and talk happy talk the whole time, but still not really liking it! Then he got to where he would bite me when I put his harness on him if it was walk time or if he even thought it was!
I really want him to love walking! So, I have a new plan for this spring! I am going to take him to the park, just him and me. Sit on a park bench for about 10 minutes or so. I'll have his toys, some treats, and try to make it fun for him! I don't know if it will work, but I've nothing to lose!
I think part of him not liking walks is because hubby is a couch potato, too and they hang out together a lot!!
