Even if your IG puppy has been bred well and has good bone density, they can still have broken legs and fractures. Prevention is absolutely necessary. Especially between 4 months to 12 months.
Prevention Puppies must be closely supervised. They need to be confined to a safe room or crate. When you can not give them constant supervision. Proper nutrition, keeping your puppy in good physical condition and letting him run in a safe area in your yard to build muscles will help with prevention.
Accidents happen quickly. Do not allow your puppy on the furniture. Play with the pup on the floor. Jumping off beds, chairs and sofas is a major hazard.
They can jump out of your arms when you are standing. They can easily break both legs if they fall from heights. Puppies wiggle, please don't walk or stand up with your puppy. Keep puppies on the floor.
Italian Greyhounds are famous for flying. If they are doing this, it is better to let them finish the jump because if you say something, at that point it may result in a worse accident. Be especially cautious of steps, balconies, and decks. Keep in mind they can climb over baby gaits. I know one puppy that broke a leg climbing. Also, X-pens without a topper can be dangerous as well as open wire crates without the top closed.
Italian Greyhounds are very good at climbing. They can easily climb over the top and break a leg.
