Hi! I just put down my deposit on my new baby! He is due to come home mid jan at around 8 weeks old. I’m so excited I have been searching for collars and harnesses just to help me contain my excitement and be ready for his day to come home. What size should I go with? I’m guessing he will probably be around 10-15lbs? I want to get a collar and a harness, most likely a step in. I want to buy one that fits but can fit for hopefully a little bit. Help please! Also, I haven’t owned a puppy in 15yrs, I know they like to wait to neuter now. Should I wait about 2years to neuter for all the growth plates to be almost done?
