Thanks for responding, sorry for the delay, got caught up in holidays.
Regarding his potty training, he's now accustomed to going outside and he's patient while I get him in his harness first thing in the morning. He's had an alarming number of accidents still, so I'm decreasing the amount of time between potty breaks and hoping that will work.
He's still chewing on everything, even a bit defiantly. I have to repeatedly tell him no not to chew on things but he just keeps on chewing it and I have to fight to get it away from him. Most recently it's a throw blanket I sometimes curl up with on the sofa. I wonder if he thinks I'm playing with him when fighting to get stuff away? I read somewhere recently that "no" is too soft a word to be corrective, so I'm trying that sharp-nasal "unh unh" sound to see if he'll respond better.
He's still struggling to socialize. With the extra walks he's meeting more dogs in the neighborhood and though I try to encourage him he still won't go near them. He hid from family when they were over for the holidays. His class resumes this coming weekend so I hope he'll feel more playful with the puppies he's already met.
The treats I have are the Pet Botanics Mini Training Treats and the package states they're 1.6 calories each. Rico loves them. I get all three grain-free flavors, pour them into a big ziploc, and shake them up. He never knows what flavor he'll get and he's always excited. I try to do three training sessions a day with ten treats each. I guess... at nearly 18 weeks, according to this caloric needs formula
he needs about 330 calories per day. Does that sound right? If I average over a week his 3/4 cups Fromm's Puppy Gold (≈315 calories), treats (≈48 calories), and bully stick (≈145 calories), he's coming to ≈384 calories a day. Is this too dangerous an overage? Should I cut back somewhere?
