Puberty in dogs comes at 6 to 18 months, occurring slightly later in males than in females. In wolves puberty occurs at about 2 years. In studies of Beagles, the first ejaculation occurred around 33 weeks of age. Early ejaculates have large numbers of abnormal spermatozoa, but these numbers soon decrease.
Dogs May Hump for Sexual Reasons You may see a female dog lift her tail away from her genitals just as she would if in heat and preparing to mate. Male dogs may ejaculate after humping, though if they're neutered, of course the fluid contains no sperm.

Canine vocalizations usually begin around 2 to 3 weeks of age, following the period where a puppy's eyes and ears are opened. Your puppy's first vocalizations may be grunts and whines; around seven or eight weeks, these will develop into yips and barks, although some dogs wait until closer to 16 weeks to start barking.
Puppies will usually begin shedding their puppy coat at around 4 to 6 months of age, but this shedding could start as early as 3 months of age. During the shedding process, a puppy may look a little unkempt until their adult coat comes in fully. For some breeds, the adult coat takes a long time to come in.
Dogs can begin urine marking at three months old. Some dogs urinate on objects while raising a leg to leave a message to other dogs. Other times, dogs may urine mark for medical or other reasons.
