My dog is a bit skittish outside and hesitates to come to me when I want to put the leash on him, I've been using his recall command to leash him and he comes to me very slowly. Do I need to make any adjustments or give corrections?

Hi Cindy! I'm training my dog on the recall command. I'm also working on getting him more comfortable outside as he can be skittish. For a while, my dog would hide underneath the dining table if he anticipated that we are going out for a walk. I believe he's slowly making progress and he's getting more comfortable outside. When we go out for walks, I would let him know ahead of time that we are going out for a walk and then I'll give the recall command to put the leash on him. Sometimes during the recall, he comes out from underneath the table, comes towards me and he hesitates for about 5-10 seconds (he's thinking) and makes his way towards me. I understand that he may be a little afraid to go outside, which is why he's hesitating. In this case, can you let me know if I need to make any adjustments or corrections? I believe I should not be correcting him if he's (slowly) making his way towards me. Thank you.

Thank you! I appreciate the advice!
