We used to take our maltipoo to the large dog park in Redmond. Now, we get out of the car and as soon as the dog gets in the first part of the park, he will go no further. Three times we tried. We don’t take him to dog parks at all any more.
I forgot to mention.. Trust your dogs instincts as well.. I would have given up after 3 attempts, too.. Maltipoos are generally brave.. Something must have been up for him/her to react that way.
There is a small dog area at the park I take my 10 month old Border Collie/Sheltie mix.. He usually tries to play with every dog there.. Except for two dogs he won’t go near..
