Bitch has come into season 4 months after last one. Vet thinks she might have ovarian cysts. At least I thought she had come into season, but vets this morning have found she has an infected anal gland and the blood had possibly been coming from her bum! Im wondering if there are two problems here as she was dropping small drips of blood like a season, and bhaving restlessly like in her last season, but 2 weeks on her vulva isnt swollen and no blood this morning . Are there any other signs that she might have a cyst/tumour? I have no experience of bitchs seasons previous to this dog.
