I have 4 dogs, all rescues and recently found two week old puppies at my work - which we bottle fed and now they are 9 weeks. ALl my dogs are mutts; 1 hound, lab mix, basenji, and Chihuahua type but bigger. My basenji and hound have gotten into random fights maybe once every 3-6 months (please note my hound was attacked by four dogs prior and hurt badly). The basenji is the top dog in the house. Recently the two fought and usually I can put them back together within 30 minutes are they are OK. This time they fought again - open wounds, etc. So now we are three weeks later and I still cant put then back together. I tried with both dogs on a leash but they went after each other again. I would like a nice harmonious household. Can you help?
