Like the title says, if you'd bring a dog 500/600 grams under his ideal weight, would it lose its ability to bite hard? Got two people telling two different things.

ps: What other things can you guys mention about bringing a dog under his ideal weight besides being to low on fat reserves to sustain a long time.

ps2: This might be a fun one, would you rather bring a dog 500 grams under or above his ideal weight (if you had to), depending on which type of dog?

Of course this is all theoretical
