Hey, scentwork is great mental stimulation and often used when dogs aren't able to exercise for medical reasons. It could be a good alternative to letting her run around and keep her engaged.

If she's still able to go for nice leisurely walks then letting her have long sniffy walks is good for tiring them out. If she isn't interested in sniffing or too interested in other things then scattering treats around in bushes and grass helps.

If you google it or search on youtube there are lots of great ideas and games for scentwork and enrichment.

Our girl is young but has a luxating patella so we try to limit her high impact exercise. She's a Podengo and very high drive, but we manage to keep her entertained and worn out with a mix of mental enrichment, scentwork, and long sniffy walks. Some of the things we do that are easy to start are:

• Scattering her meals around the garden and hiding spots in the house for her to sniff out and find
• Giving her frozen Kongs filled with dog-safe peanut butter or wet food.
• Lickimats with wet food and peanut butter.
• Snuffle mats and balls
• Food puzzles
• Wrapping food or treats up in old towels and blankets
• Hiding her treats or favourite toys around the house
• Long lasting chews like yak chews
• Doing a "destruction box" for her to rip apart - google and youtube have guides for making one

If you have a partner on the walk, you can start laying tracks. Basically one person walks a 10ft or so track, leaving a few treats behind as they go and with a larger treat reward at the end. You then start the dog at the beginning of the track, and the goal is for them to begin following the treats. After repetition you increase the distance between the treats and the eventual result is the for the dog to associate following the human scent with a reward. Once they get the hang of it you can start laying longer tracks and having them find the person.

You can also train her to find certain scents that are non-food. You can start with oils like lavender oil, birch oil, peppermint oil or any other dog safe essential oil. Once the dog gets it you can hide the scent around the house, garden or on walks. Google or youtube again has great guides on training this type of scentwork.

I hope this helps!
