Do puppy ears change?
The cartilage at the base of a standing ear will begin to start feeling firm by 4-to-6 weeks old.
However, My New German says it can take as long as six months for your dog's ear cartilage to harden sufficiently for his ears to stand up.
How long do I wait before taking my puppy outside? Vets recommend waiting until 10-14 days after your puppy's last vaccination booster – usually at around 14–16 weeks of age – before introducing them to the wonders of local parks, beaches and walking trails.
A good rule of thumb is a ratio of five minutes exercise per month of age (up to twice a day) until the puppy is fully grown, i.e.
15 minutes (up to twice a day) when three months old, 20 minutes when four months old etc.
Once they are fully grown, they can go out for much longer.
By around eight weeks of age your puppy should be eating solid food.
Puppies should be fed three to four times a day therefore if you are currently feeding ¾ a cup of puppy food twice a day you should consider spacing it out by feeding ½ cup three times a day.
