My husband and I were out of town one week end and we left our two dogs at his mother’s. When we got back they had fleas. So I give them a bath and put Hartz advanced flea collars on both of them. They were fine that day. We put them in thier kennel that night. The next morning they were fine but Dipsy the oldest one was scratching alot. I didn’t think any thing about just thought she had a few bites on her. We had to go some where and we put them back in the kennel and when we returned Dipsy had chewed her collar off. She could barely walk by this time. It was late that night and I didn’t know what to do. She is my baby and I just started panicing. My husband started calling trying to find a vet to see her. An hour had pasted by the time we found and Emergency number. We rushed her to the vet. They had to give her three shots and evaluate her afterwards to make sure she didn’t have an allergic reaction. This costed us $225.00. That might not seem that much, but it is to us. My husband and I work very hard to make ends meet. That ended up being our house payment and now we are behind. If I had it to do over again I would. I would pay anything to save my dogs. They are my children and they are treated as babies.
