Rule 2: The oxidation number of an ion is the same as its charge. An ion is an atom with a charge due to gain or loss of electrons. The charge is indicated as the superscript (small number at top right) after the atom. If an atom has this, then this means that it is an ion.
If the breeder is saying that there is nothing wrong with this pup, and that not being able to walk is normal, then please, PLEASE move on and go to a different breeder...this one is out and out dishonest... phrannie. ANSWER #4 of 8. yes like phrannie said they usually start walking at 2-3 weeks. So yes there is probaly something wrong with that puppy. Check out the others and if they can't walk either then don't believe what the breeder is telling you. Also take a look at the parents.
The first exciting solo steps may be taken, though it's normal for toddlers to walk any time between nine months and 17 and a half months (Sheridan 2014). Your child's outstretched arms while she walks help her to keep her balance. 14 to 15 months. Most toddlers can walk at this age. Your child may enjoy push-and-pull toys (Sheridan 2014), such as toy trucks or animals on wheels, and she may even be able to walk backwards. Ask for help if ... your toddler isn't walking by 14 months or 15 months, you could mention it to your health visitor or doctor if you have concerns.
