Infections and problems of the anal gland are very common in dogs and it sounds like this is what your dog is suffering from. Impaction of the anal gland can occur when it fails to naturally empty because of soft stools or an overactive gland, and secretions become thick and pasty. Anal gland impaction is treated by manual emptying of the glands. Ask your vet for advice on how to proceed – you should act quickly before they become infected.

When anal glands become infected there will be small amounts of blood or puss in the secretions. If your dog is scratching his bum on the floor very frequently, it may be his glands are already infected. Treatment is the same as for impacted glands, but is followed by an antibiotic wash at regular intervals for a period after the manual emptying.
