I don’t see anything wrong with putting on a doggy jacket or sweater on your dog. I put shoes on Rai the other night for our walk so he would adjust to them just incase I ever need to use them. And sometimes he is a shivering when I put him out to go potty ( and we are in CA- so it’s not that bad). I figure if he sleeps under the blankets with me on the couch he must get chilly outside so if he needs a lil extra so be it. I actualy saw a black and white camo one on petsmart.com I been debating buying. Plus the more things one lets their dogs experience the more rounded their personality will be and accepting of things that are not “normal”.
