What to do:
Brushing your Maltipoo's teeth will remove this sort of smell and also serves the 2 great benefits of keeping up with good oral hygiene (decay in a puppy tooth can cause problems with the adult set) and the feeling of the bristles on the gums can be very pleasing to a Maltipoo puppy that is suffering from intense teething itch.
Odor from the Ears
One of the last things that an owner wants to happen is to notice a bad smell coming from a
Maltipoo's ears, since this is never a good sign. While there can be a buildup of wax, this alone does not often cause an odor. More likely, this will be a matter of some type of infection. This can be a yeast or bacterial infection or even ear mites that should be treated by the vet.
Once treated, keeping the ears free from excess moisture (place cotton in the outer ear canals when bathing) and keeping excess wax under control can help prevent this from happening again.
Odor from the Vagina
This is often a matter of a Maltipoo's vagina smelling like fish or having a strong musty smell. It may be more noticeable after the dog urinates, though the smell can seep into fabric and leave a lingering odor on the dog's bed, the sofa, and other areas where she rests.
She may lick the area and there may be signs of localized swelling or red, irritated skin. There may or may not be clear or white discharge.
Ongoing smells like this are often due to vaginitis, which is an infection of the vagina. This may be bacterial or yeast. Another issue that can produce this sort of smell is a urinary tract infection or a bladder infection (these can also make the urine smell quite bad as well).
With young female Maltipoo dogs that have not yet had their
first heat cycle, this may be an issue of juvenile vaginitis. This can develop with young female pups and if so, spontaneous goes away after the first heat.
In any case, diagnosis should be done by the veterinarian to determine the course of treatment. Antibiotics are given to treat vaginal infection and this is done after testing to make sure the right one is prescribed; the wrong one (or a broad-spectrum one) can make it worse as it will not correctly target the specific bacteria that are involved. Chronic cases may also be treated with a non-diary probiotic to maintain proper levels of both 'good' and 'bad' bacteria.
