I have used it to no ill effect but would not feel it a permanent solution. Pepsi is five now and after a very hairy C-Section when she bled like a stuck pig and we nearly lost her. I would have liked to have her spayed but the vet was wary due to her reaction. Now I let her have one season then inject prior to the next so we only have one a year. This is easier to cope with with three bitches in the house. I did have the whole lot done two years ago when they had to stay with a friend who has two dogs and they were all due in and have not had any problems since then, they all came back in the next due time and Merlot had a lovely litter of nine no problems. But you really need her to settle into her routine for a couple of years before making any hasty decisions, she may settle to a longer period as she matures.
