Amber gave a Lot of great advise!
-Crates are also great for separating dogs when feeding. Some dogs like to "cave" for comfort and security.
-Besides leashes and collars of various sizes, I also use the "double" or Y leashes for walking 2 mid size and larger
dogs together. Holding 1 or 2 leashes instead of 4 is so much easier.
-And, I have the chest "stop pull" or "no pull" harnesses. Some of my customers have dogs that use the nose "friendly leader", but they can't sniff with the other dogs or forget to bring the No Pull for their high energy dog.
-Don't forget the poop bags. I use them on walks and the plastic grocery bags for picking up in the backyard.
**Toys should include balls of various sizes, kongs, and anything else that looks like fun. Just be warned, most stuffed toys get ripped/torn apart and the stuffing strung all over.
*I get some things at Walmart "when on sale", but also keep checking Ross stores for items.
*Don't forget to check all the Thrift/Resale stores for dog items.
*You can sometimes find child gates, vacuum cleaner for "pet hair", crates, etc. for a great price;
*And, check CL under- "FREE", "Farm & Garden", etc. Just make sure you check the prices for New first before paying someone on CL.
Hope this didn't over whelm you. You don't need to buy extra leashes, collars and some other things right away. It depends on how many dogs you plan on taking at one time. Watch for sales (Ross and a Christian Charitable Thrift/Resale are my Favorite Stores) These seem. to accumulate very quickly. I have had friends and customers "give" me doggie beds and items because they were buying new.
Have Fun and Welcome!
