injury

Hello all :) I was hoping to get some advice on vitamins. I am getting a 6 month old mixed breed from Romania soon. She had a previous broken leg that's all healed up nicely. The vet in Romania says she needs minerals and has her on phosphorus, calcium and vitamin d. I've ordered a supplement...

As the title says, my chihuahua accidentally banged his head on my elbow! He seems fine, it's been 30 minutes and there's no change in behaviour, should I be worried for a cracked skull or head injury? Please help!
