If you always have trouble with dogs try this strategy.
This strategy can be hard to do if you are inexperienced but if you are experienced its sad you can't get past the dogs. But when you start you don't buy any weapons and just knife the first round. you need at least 4000 points to do this so stay in the first room until you have those points. Another thing don't buy the mystery box if you find it OK. When you have the 4000 points you just need to open the doors on the upstairs right side. then head through to the next room which I think cost like 1250 points. Once you go through and down the stairs walk through the opening and head to the left.there you should be able to buy the stakeout and buy the stakeout. once you have it the zombies should be coming and just start blowing them to pieces. You want to stay in that room until the first wave of hellhounds come. Once you here "Go Fetch me their souls" that means that dogs are coming. Head down to the bottom part of the room you opened and head into where there is another door. Just camp back there and with the stakeout. You want to reload the stakeout ASAP when the dogs aren't coming because it takes a long time to reload. It helped me out. The stakeout has always helped me with the dogs. Well thank you for reading this post and hope that this works for you. It worked for me and helped me get really far.
Please tell me if this helped you I like comments and well change stuff I think is absolutely reasonable.
