Veterinary questions? Ask a Vet for Answers ASAP
Sorry to hear this. If the bandages are soaked through with blood then they will need to be changed, the wound may also need suturing if the bleeding has not stopped with a bandage alone.
If you contact your vet they should be able to arrmage to see him through their out of hours service tonight.
Please let me know if you need any further help or advice.
