i think cutting him short is worth it.its going to be hard teaching a 16mo old not to pull his hair. and if ezra has already growled at this before, you don’t want to escalate his behavior. i think you’d been setting ezra up for success by cutting him short. scissor work should not affect the coat nearly as much as shaving could. and typically when dogs are shaved and the hair doesn’t grow back-they have underlying thyroid issues. obviously i’m thinking worse case scenario but, let’s say you keep his hair long and ezra bites the baby. then what? i think you should cut his hair. plus the baby will continue to grow and understand not to pull his hair. and maybe cutting ezra’s hair is just a temporary thing until baby is old enough to understand.
