Dog Walking needed near Bilsthorpe NG22

We have two miniature schnauzers who are 2 years old. They're both smart, sweet and affectionate but we feel they would use a bit more stimulation during office hours. Matt (my hubby) works from home and I do for part of the week. We find they bark at every little sound in the house, which happens far less when they've been stimulated with a walk for a while. So, this is worse during the middle of the day. We're also catching up on training them, as Teddy had a liver shunt as a puppy, which took priority above their training needs while they were young (they're brother and sister from the same litter). His shunt is only partially repaired, so he's fed on a diet that's low in animal proteins to help with this and he tends to drink a little more water than his sister. Teddy will be castrated in the next few months, but his sister (Muffin) has been spayed. They're both reactive dog's who become easily scared, startled and can get easily nervous around unknown people and other dogs. Therefore, we're hoping that, by enabling another walk part way through the day, they will get some extra practice at keeping focus on their walker instead of any triggers, and they can socialise more. Their recall is pretty good but tends to drop off more when their stress is heightened. Please let me know if you have capacity to walk them both part way through the working day Monday to Friday and any other information you can provide about this. We live in Bilsthorpe.
