Hi my little Jack Russell is 12 years old now and still in good shape but recently I have come to find hard lumps under her skin around her nipples and up and down her stomach she loves a belly tickle and sometimes am scared I find more. I have noticed one getting bigger over time and I don't want to loose her yet. Me been me I Over worry and would love for someone to put my mind at ease. Thanks for taking the time to listen and help. Regards vikki

These sound like mammary tumours (similar to breast cancers). Please have her assessed urgently as surgical removal may be recommended as soon as possible as long as there is no evidence they have spread internally
