Any dog shampoo you can find (yes, even at Walmart) is going to be fine. Choose whichever type you prefer. Shampoo has less overall effect on itching, etc. than making sure its ALL rinsed out. On a collie, that is going to be a chore. Be sure you have plenty of water pressure and I wouldn't recommend using something to pour water over her..You are going to need the pressure of a sprayer to get all the shampoo out. I would use a conditioner too on a collie. Any pet conditioner will work, I prefer Coat Handler (cannot get at petstores or Walmart) and use it exclusively, because I don't find others to be effective, but maybe someone else can recommend a good conditioner for you? Again...rinse, rinse, rinse...Then rinse some more.
Yes, your dog's coat will benefit from using a brushout spray when brushing and combing. I would not use the aloe gel and water though. Its going to leave a residue, and make her feel sticky and gunky over time. If you cannot get a spray made specifically for dogs/brushing, then I would just dilute down some conditioner...Dilute it very well..Just enough conditioner in it to give it the scent and some slipperyness to the water..Does that make sense? I would give you a ratio, but different conditioners are going to need different ratios. Ideally, a spray made for dogs is best. Most are not that expensive, especially when bought as concentrate and diluted down.
