Hello, I am in need of help with my pup. He is a 3-year-old Terrier Mix we adopted at 8 weeks. He is fun but yet a picky eater. He does use pee-pad and trained very well to identify area where he is assigned to go. I could use some help on training in general when walking him...he likes to bark but he is friendly. I take him to Smart Parke once in a blue moon when I need the help, but it can add up. Just looking for help from time to time.
