Hi Alanna, welcome! It was so great talking with you on the Tripawds Helpline . I can tell you'll make a pawesome Tripawd parent just by the way you are reaching out for info before committing to adopting this sweetie. To recap our conversation here's what I mentioned:

• Younger Tripawds of less than a year old may encounter more issues as they age. If bones aren't done growing, compensating for that missing limb can cause issues in the future like elbow dysplasia. We were recently told this by an orthopedic vet. 
• However, you can do many things to delay the onset of joint and bone issues, such as: monitoring the dog's activity to ensure he gets the right amount and type of exercise and keeping him slim.
• Tripawds don't necessarily "need" prosthetics . But if a dog has much of the limb remaining, it's worth investigating. Prosthetics can absolutely give an improved quality of life for the dog who adapts to them, and the human who can invest the time and money into the devices.
• The best thing for any Tripawd is to emphasize mind games like Sniff-It, obedience, canine nosework and other activities that tire out the dog's brain over their bodies.
• Look into a consult with a certified canine rehab therapist to understand what this dog's needs are and how to meet them. The best part is the Tripawds Foundation will even pay for your first rehab visit !

We are so glad you are thinking of adopting this dog and hope to see you back here again with news that you got approved. If you have any other questions don't hesitate to ask.
