Habituation model

since you measure the same dog several times its measurements are 
correlated and you should take this into account in your analysis 
(i.e., "aov()" is not appropriate in this case). Probably you could 
find functions "lme()" and "gls()" in the "nlme" package very useful 
for your problem and for which a very good reference is:

@Book{pinheiro.bates:00,
  author    = {J. Pinheiro and D. Bates},
  title     = {Mixed-Effects Models in S and S-PLUS},
  year      = {2000},
  address   = {New York},
  publisher = {Springer-Verlag}
}

I hope it helps.

Best,
Dimitris
