Um I can't help too much but I will try! I am in the same boat I have another new baby joining my porscha in about 3 weeks so I am thinking about the same things.
This is what I think....bathing I bath porscha 1 to 2 times a week depending on what she has gotten into! If she has gotten into mud or something I will wash her right away if she has been out of trouble for a few days I wait for a while. I let her face and ears get wet but not like direct spray on them, using a wash cloth on those areas works out well.
Age of brushing teeth not sure but I think the sooner you get them use to it the better. I would use two different brushes just incase of any spread of illness.
Porscha started heartworm I think at like 3 months? It was one of her first few vet visits.
Flea control I wouldn't buy anything unless you need it or think it may be a problem.
Hope some of this helps! |
